Michigan’s G.O.P. Nominating Process Appears Headed For Chaos

As early in-person voting began on Saturday in Michigan, a fight for control of the G.O.P. in the crucial battleground state plunged Republicans there deeper into a political maelstrom, with rival factions potentially barreling toward hosting dueling nominating conventions.

As if things weren’t already confusing.

In a little over a week, the state will host a traditional primary on one day, and then a caucus-style convention a few days later. Now, it seems, there could actually be two conventions, in different parts of the state, each claiming legitimacy.

Former President Donald J. Trump is headed to Michigan on Saturday night, with a campaign rally in Waterford Township, about 30 miles northwest of Detroit. While he has made it clear which faction he is supporting, and so has the national party, that has done little to dissuade the Trump-styled election denier attempting to hold on to power.

The feud, already being waged in state court, appears to be only gaining intensity.

Pete Hoekstra, whom the Republican National Committee recognized on Wednesday as the state party’s rightful chairman after his election last month, said he was moving forward with plans to hold a statewide nominating convention on March 2 in Western Michigan.

But Kristina Karamo, defying the R.N.C.’s determination that she had properly been removed as party chairwoman earlier in January and Mr. Trump’s endorsement of Mr. Hoekstra, has also indicated that she will continue hosting a convention on the same day, for the same purpose, but in Detroit.

At stake at the convention will be 39 of Michigan’s 55 Republican presidential delegates. The other 16 will be decided during the state’s Feb. 27 primary, which includes at least nine days of early voting. The hybrid process, new this year, was adopted by Republicans in order to comply with R.N.C. rules after Michigan’s Democratic governor moved up the primary date.
