Michigan GOP Candidate Petition Guide • 2026 Cycle • Based on BOE July 2025 Manual

How Republican Candidates Qualify for Michigan’s 2026 Primary Ballot

This is the Michigan Bureau of Elections partisan petition manual reorganized into an operator’s guide for Republican candidates and campaigns: clearer order, faster navigation, modern layout, and decision-ready checklists — while preserving the manual’s rules and instructions.

Overview

For: Republican candidates and campaign teams seeking nomination for Michigan’s 2026 primary ballot.

Scope control (important)
This page covers the Michigan Bureau of Elections partisan petition manual process for major-party candidates: petition format rules, signature validity rules, filing location rules, and Board of State Canvassers review procedures as described in the July 2025 manual. We do not publish independent/minor-party (“third party”) filing steps here.
Context (why this still matters beyond the primary)
Even if your campaign is Republican, independent/minor-party filings can affect general-election ballot composition and downstream messaging. This guide stays strictly on the BOE major-party manual process.

Source authority: Michigan Bureau of Elections petition manual approved July 31, 2025 (plus Michigan Election Law citations included inside the manual). This guide preserves the manual’s instructions but improves readability, flow, and navigation.

Last updated for this page: Manual approved July 31, 2025. Always confirm any subsequent BOE updates before filing.

Campaign workflow for ballot access (GOP candidates)

A practical campaign sequence that tracks the manual’s requirements and how reviews occur in practice.

1

Confirm your office + nomination method

Petition (most offices) vs convention nomination (some statewide offices). Identify whether a $100 filing fee option applies.

2

Confirm where you must file

Secretary of State vs County Clerk depends on district geography (single-county vs multi-county districts).

3

Lock the petition form layout before collecting

Heading completion + warnings + font sizes + 8.5×14 landscape + correct certificate language are “fatal defect” territory.

4

Train circulators and run quality control

Most signature loss is preventable: address format, city/township entry, date-of-signing (not DOB), and the circulator certificate.

5

File early and file surplus (without exceeding the maximum)

The manual urges campaigns to gather more than the minimum. The law also sets a maximum number that may be filed.

6

Prepare for canvass and challenges

Sampling, FOIA copies, and challenges follow structured procedures and timelines (see “Canvass & challenges”).

Campaign reality check (manual-consistent)
Even with professional collection, expect some invalid signatures and possible sheet invalidations. Build margin into your plan.

Signature requirements: how many + what makes a signature valid

  • Governor: 15,000–30,000
  • U.S. Senate: 15,000–30,000
  • U.S. House: 1,000–2,000
  • State Senate: 500–1,000 (or $100 filing fee option)
  • State House: 200–400 (or $100 filing fee option)
Statewide filing instruction related to congressional districts (manual)
For statewide partisan nominating petitions, the manual instructs petitioners to provide a separate sample demonstrating signatures of at least 100 registered voters in each of at least seven congressional districts when submitting statewide petitions.

Sources: Manual Appendix A + statewide filing instructions section.

The manual describes signer-line expectations and how filing officials evaluate entries against the Qualified Voter File (QVF).

  • Signature: should reasonably match the QVF signature; perfection is not required.
  • Printed name: recommended for clarity; omission can be an “acceptable variation” when other required fields are present.
  • Street address or rural route: must include house number + street name. P.O. Box is not acceptable.
  • City or township: signer should write the city or township of registration/residence.
  • Zip code: requested but omission/incorrect zip can be acceptable.
  • Date: signer must write month/day/year of signing. A common invalidation issue is a signer entering date of birth instead.
Multiple petitions for the same office (manual rule)
If a voter signs nominating petitions for multiple candidates for the same office when only one person will be elected, only the earliest dated signature is counted. Later signatures are invalid — even across different parties.

Sources: Manual signature-line guidance + individual signature validity sections.

The manual explains that a signer may write a “postal address” community name, but validity depends on whether that name properly corresponds to the voter’s registration jurisdiction.

  • Some voters may validly write either their township name or a shared postal community name (manual examples discuss Mt. Morris postal naming across multiple townships).
  • An entry can be invalid if the signer writes a community name that does not correspond to the voter’s registration jurisdiction relationship as described in the manual’s examples.
  • Unincorporated place names can be valid if the voter is registered in the township containing that place.

Source: Manual “Validity of individual signatures” and “Jurisdiction name variations” sections with examples.

Petition form rules (format requirements that can sink a filing)

Non-negotiable principle (manual)
If a nominating petition heading does not comply with Michigan Election Law requirements described in the manual, signatures on that petition are considered invalid and not counted.
  • Sheet size: must be 8½ × 14 inches.
  • Orientation: must be arranged horizontally (landscape).
  • Signer warning: must be printed in 12-point boldface immediately above signature lines.
Signer warning text (as printed in the manual)
WARNING – A PERSON WHO KNOWINGLY SIGNS MORE PETITIONS FOR THE SAME OFFICE THAN THERE ARE PERSONS TO BE ELECTED TO THE OFFICE, SIGNS A PETITION MORE THAN ONCE, OR SIGNS A NAME OTHER THAN HIS OR HER OWN IS VIOLATING THE PROVISIONS OF THE MICHIGAN ELECTION LAW.

Source: Manual sheet-size and signer-warning sections (MCL citations included in manual).

The manual prints Certificate of Circulator statements and includes the nonresident checkbox language. Operational points:

  • The “CERTIFICATE OF CIRCULATOR” heading is printed in 12-point bold and the statement itself is printed in 8-point type (manual).
  • Nonresident checkbox rule: If the circulator is not a Michigan resident, the circulator must mark the nonresident box. The manual states failure to mark it makes signatures on that sheet invalid/not counted.
  • The circulator block must include a complete residence address (street/rural route, city/township, state); a P.O. Box is invalid.
  • The circulator must sign/date the certificate after circulating; the manual warns not to sign/date until after circulation.

Sources: Manual certificate text + circulator block validity section.

  • Circulator instruction (manual): printed in 12-point boldface: “CIRCULATOR—Do not sign or date certificate until after circulating petition.”
  • Circulator entry spaces beneath that instruction are presented in 8-point type (manual).
  • Sponsor imprint (manual): petition must include, in 8-point type, the name and address of the candidate committee paying for printing, preceded by “Paid for by the committee to elect ______.”
  • Type size caution: the manual notes that software “font size” may not equal printed type size; sponsors must ensure printed type measures the required type size.

Source: Manual sections on circulator instruction, sponsor identification, and type size.

The manual states BOE can provide limited informal review of petition headings (and can check font size with a physical copy). It is not formal approval.

  • Heading review can be done by email (manual).
  • Font size review requires staff to receive a physical copy (manual).
  • In-person font review requires an appointment by emailing File-Canvass@Michigan.gov (manual).

Source: Manual “Staff review regarding form requirements” section.

Appendix B: signature verification guidance (examples)

Appendix B illustrates examples the manual describes as recommended valid vs questionable. It also notes legitimate reasons signatures vary (haste, clipboard, age/health, pen differences, size differences).

  • Signature appears shaky/trembling (possible health/age); described as valid.
  • Only parts match (e.g., first letters) but still has redeeming qualities; described as valid.
  • Partially printed but partially matches signature on file; described as valid.
  • Recognized diminutive of legal name (e.g., “Bill” for “William”); described as valid.
  • Signature style changes slightly over time; described as valid.

Source: Manual Appendix B (“Signature Verification Examples”).

  • Signature entirely printed when signature on file is entirely cursive; flagged as questionable.
  • Signature differs in multiple, significant, obvious respects; flagged as questionable.

Source: Manual Appendix B and “Signature verification” section.

Circulators: training + quality control (Appendix C)

  • Write the county of circulation in the heading and verify signers are registered in that county.
  • Ask potential signers whether they are registered to vote.
  • Require street address/rural route where indicated; a P.O. Box is invalid.
  • Remind signers to write date of signing, not date of birth.
  • Review each signer entry for completeness; have signers fill missing blanks.
  • Encourage signatures that reasonably resemble the voter’s signature on file (Appendix B examples).
  • After circulation: ensure the circulator signs/dates the certificate and completes required information; nonresident circulators must check the nonresident box.
Paid circulators (manual guidance)
The manual advises sponsors to research circulator companies, check work quality, and periodically review collected sheets during the collection period.

Source: Manual Appendix C (pages labeled “Partisan Petition Manual | 33–34”).

The manual warns that several Michigan cities/villages cross county boundary lines. Circulators should ensure the voter signs the petition sheet aligned with the voter’s county of registration.

Source: Manual Appendix C “Crossing county lines.”

  • Implement QC before filing; the manual encourages obtaining the QVF for pre-filing verification.
  • Signatures found invalid during QC may be crossed out prior to filing; crossed-out signatures are excluded when determining the maximum number filed.
  • Review all sheets for completeness (especially county of circulation and certificate of circulator).
  • Gather and file more signatures than the minimum; note the law sets a maximum number that may be filed.

Source: Manual Appendix C quality control section.

Canvass, FOIA copies, and challenges (Board of State Canvassers)

  • For statewide partisan nominating petitions, the manual recommends sorting petition sheets by the number of valid signatures on a sheet and labeling boxes accordingly.
  • Provide a separate sample demonstrating at least 100 registered voters in each of at least seven congressional districts (manual instruction for statewide submissions).
  • Do not pre-number sheets; BOE applies sheet numbers per a Board-approved process.
  • Unique identifiers may be placed at the bottom of each sheet; do not place any identifier in the top right and do not cover mandatory elements.

Source: Manual “Nominating petition filing instructions” section.

The manual states copies of petitions may be requested under FOIA and references a Board-approved electronic scanning and numbering plan intended to improve efficiency and FOIA responsiveness.

Source: Manual “Board of State Canvassers petition review” section.

  • Under Board practice described in the manual, challenges are due 7 days after release of the sample.
  • A sworn complaint alleging insufficient valid signatures or other defects may be submitted within 7 days of the filing deadline (manual).
  • Signature challenges must be notarized and submitted to the Bureau of Elections.
  • Manual strongly encourages submitting a scanned notarized challenge by email to MDOS-Canvassers@Michigan.gov.
  • To be considered at a Board meeting, material should be received at least 48 hours before the meeting (manual).
Best practice (manual)
Serve a copy of any challenge upon the party being challenged at the same time the challenge is submitted.

Source: Manual “Submitting the challenge” section.

The manual says a challenge must specify each challenged signature and the reason. It instructs challengers to cite the sheet number and line number, and recommends organizing in sheet order and submitting in Excel/CSV format to expedite processing.

# challenged Sheet # Line # Challenge reason Explanation
114NRVoter not registered
2569IAInvalid address listed
3721DATEVoter signed with date of birth
Challenging something other than specific signatures
The manual states you must provide a full written description and specify the sheet numbers involved.

Source: Manual “Challenge procedure” section.

  • Manual describes a single-stage random sampling process using software.
  • Sampled sheets are face-reviewed first to determine whether a sheet-level defect invalidates the entire sheet.
  • Sampled signatures on valid sheets are then checked for registration and other validity criteria.
  • Invalid signatures are reviewed a second time by another BOE staff member (manual).
  • BOE prepares a staff report; the manual states the report is posted online at least 2 business days before the Board meets to make a determination.

Source: Manual “Procedure for evaluating petitions” section.

Invalidation rules (what kills a sheet vs what is an acceptable variation)

Key distinction
The manual distinguishes between (1) sheet validity problems that can void an entire petition sheet and (2) signature-level problems that void only an individual signer entry.

Heading defects (countywide form)

  • County of circulation omitted.
  • Two or more counties listed, or a county not located in Michigan listed.
  • Required candidate/office information omitted (candidate name, residence address, party affiliation or indication of no party affiliation, office sought, district served if any).

Circulator certificate defects

  • Circulator signature missing (manual notes printing name only without signing can invalidate the sheet).
  • Circulator date omitted/incomplete or earlier than the date entered by every petition signer.
  • Circulator residence address omitted/incomplete or uses a P.O. Box instead of street/rural route.
  • Nonresident circulator fails to mark the nonresident box (sheet invalid).

Other fatal defects

  • Damaged/torn/mutilated such that mandatory elements are illegible or omitted.
  • Mandatory elements obscured/covered by white-out, permanent marker, stickers, or other opaque material.

Source: Manual “Petition sheet validity” section.

  • For most offices, omission of “Term Expiration Date” is not fatal if the position can be ascertained; it is required where multiple positions with different term ending dates exist (manual notes judicial exceptions).
  • Circulator signature illegible.
  • Circulator prints name in signature space and signs in printed-name space.
  • Circulator omits printed name.
  • Circulator enters cursive signature in printed-name space.
  • Circulator omits zip code or enters incorrect zip code.
  • Out-of-state circulator omits county of registration.
  • Michigan resident inadvertently checks the out-of-state checkbox and/or writes a Michigan county of registration.

Source: Manual “Acceptable sheet variations” section.

The manual states a signature entry is valid when the voter signs and provides street address/rural route, city/township where registered, and date of signing.

Acceptable variations (manual examples)

  • Initial(s) plus last name (examples given in manual).
  • Illegible signature can still be valid depending on verification and other fields.
  • Printing in the “signature” space and signing in printed-name space (and similar swaps) can be acceptable.
  • Signature stamp if signer cannot sign their name.
  • Ditto marks for repeating address/city/zip/date fields.
  • Signer registered at a different street address within the same city/township on date of signing.
  • Postal community name / village / unincorporated place entries can be acceptable in circumstances explained by the manual’s examples.
  • Zip code omitted or incorrect.
Specific invalidity note (manual)
A signature can be invalid if the signer merely prints their name in the printed-name space, fails to sign, and the signature on file is cursive.

Source: Manual “Validity of individual signatures” section.

FAQ for Michigan Republican candidates

Structured, search-friendly answers based on the BOE manual’s partisan petition rules.

Per Appendix A of the manual, the filing deadline for these offices is Tuesday, 4/21/2026 at 4:00 p.m. and the withdrawal deadline is Friday, 4/24/2026 at 4:00 p.m..

The manual’s rule: if the district is composed of two or more counties, file with the Secretary of State. If wholly contained within a single county, file with the County Clerk.

The manual includes a nonresident checkbox provision in the Certificate of Circulator and states that a nonresident circulator must mark the nonresident box. Failure to do so can invalidate the sheet.

The manual’s coding categories repeatedly focus on invalid/insufficient address (including P.O. Boxes), invalid city/township entry, invalid date (including DOB mistakes), and registration/jurisdiction problems (NR/OD/IC/NC).
