In February 2023, Governor
Gretchen Whitmer signed legislation to move up the date of both the Democratic and Republican presidential primaries in Michigan to February 27, 2024, in line with the
Democratic National Committee's (DNC) state reorganization plan. The date violated Republican Party Rule 16(c)(1), which prohibits any state/territory except Iowa, New Hampshire, Nevada, and South Carolina, from holding their primary/caucus until March 1, 2024, violating any other state/territory by stripping 80% of its delegates at the
Republican National Convention. In response, in June 2023, the
Michigan Republican Party (MIGOP) passed a resolution of intent that would allocate 16 delegates based on the results of the February 27 primary and 39 delegates based on the results of caucuses in each of the state's 13 congressional districts on March 2. The convention held by the faction of the Michigan Republican Party recognized by the
Republican National Committee led by
Pete Hoekstra will be in
Grand Rapids at the
Amway Grand Plaza Hotel on March 2, while the faction of the Michigan Republican Party led by
Kristina Karamo will hold their convention in
Detroit at
Huntington Place on the same day. While media is invited to the Karamo caucus, it will be closed to the public. The RNC has indicated that only the delegates from the Hoekstra-led convention will be seated for the
2024 Republican National Convention. A court ruling by Judge Joseph Rossi on February 27 indicated that Karamo was properly removed as MIGOP chair and barred Karamo from conducting business on behalf of the "Michigan Republican State Committee or the Michigan Republican Party". Rossi made his ruling retroactive to January 6. A full trial regarding control of the MIGOP is scheduled to take place on June 10. The Michigan Court of Appeals denied a request on February 29 by Karamo to issue a stay on the court order while her appeal is under consideration, putting her Detroit caucus in doubt. The chaos affected delegates from
Michigan's 1st congressional district who had planned to go to Detroit but were barred credentials to take part in the Grand Rapids convention; a third gathering is planned the same day in
Houghton Lake. A contingent from
Michigan's 4th congressional district was also denied credentials for the Grand Rapids caucuses, so a fourth gathering was announced for the same day in
Battle Creek. The Detroit gathering was cancelled. == Primary candidates ==
