No later than Monday 15 January 2024: County Conventions

The County Conventions elect delegates to the District Caucuses. This step is not formally related to Presidential Preference.

Any Michigan Republican is eligible to participate in the primary. A registered voter declares her or his party designation by selecting a Republican ballot at the polls. The voter's choice becomes public information.

Tuesday 27 February 2024: Michigan state run Primary. Hours 7:00a-8:00p EST (1200-0100 UTC) / 7:00a-8:00p CST (1300-0200 UTC). Relatively small portions of this state are in CT and so the vast majority of the polls are closed by the time indicated ET, when the networks feel they can project. Delegate Selection: Advisory Primary. Voter Eligibility: Open Primary.

The state Convention is anticipated to use the results of the Presidential Preference Primary to bind 16 statewide delegates.

16 (10 at-large + 3 bonus + 3 RNC automatic) of Michigan's 55 delegates to the Republican National Convention are bound by the statewide vote. The state Convention is anticipated to use the results of the Presidential Preference Primary to bind these delegates. The delegates will be selected by the State Committee from a list of party members provided by the campaigns of the Presidential candidates.

• The delegates are allocated proportionally to candidates who receive 12.5% or more of the vote. Delegates = 16 × (votes for the candidate) ÷ (total votes) rounded down to the whole number. Any unallocated delegates are awarded to the highest vote getter.

Saturday 2 March 2024: Congressional District Caucuses (10A local time) and State Committee Meeting (8:30p local time). Delegate Selection: Winner-Take-Most Caucus/Convention. Voter Eligibility: Closed Caucus/Convention.

The caucuses meet to conduct a Presidential Preference Poll in each congressional district to elect 39 district delegates-- 3 delegates per district. The delegates are selected by the Congressional District caucuses.

• In each congressional district, if 1 candidate receives a majority (50% + 1) of the vote, that candidate receives all 3 delegates. Otherwise, the candidate receiving the most votes receives 2 delegates and the candidates receiving the next highest number of votes receives 1 delegate.

State Convention
Excluded from Nationwide vote.

State Convention

The caucuses elect the National Committeeman, the National Committeewoman, and the National Convention delegates.

All delegates are bound for the first 2 rounds of voting at the national convention. If there are more than 2 rounds, the delegates are unbound.

2024 Presidential Primary Calendar

The date is compliant with Democratic Party rules-- on 2 December 2022 the Democratic National Committee Rules and Bylaws Committee recommended a Michigan pre-window date of Tuesday 27 February 2024.

However, the date is not compliant with Republican Party rules. If the Michigan GOP uses the Michigan Primary to allocate delegates, the state would be subject to sanctions: "... If any state or state Republican Party violates Rule No. 16(c)(1) [beginning before 1 March] ..., the number of delegates ... shall be reduced for those states with 30 or more ... delegates to 9 plus the members of the Republican National Committee ... " [Rule 17(a)]. The state would go from 55 delegates to 12, a 78% reduction.

Circa 11 June 2023, the Michigan Republican Party passed a resolution of intent for their 2024 Delegate Selection Plan. 16 (10 at-large, 3 bonus, 3 RNC automatic) delegates would be allocated at the 27 February 2024 winner-take-all state run primary; 39 Congressional District delegates, 3 from each district, would be allocated in each of the 13 congressional winner-take-all district caucuses on 2 March 2024. Concerns: (1) The 27 February primary is before the 1 March date allowed for Michigan, and (2) RNC rules prohibit the holding multiple delegate allocation votes.

RNC Rule 16(a)(1) appears to forbid the holding multiple delegate allocation votes: the 27 Primary and the 2 March District Caucuses. "Any statewide presidential preference vote that permits a choice among candidates for the Republican nomination for President of the United States in a primary, caucuses, or a state convention must be used to allocate and bind the state’s delegation...."
