Michigan law requires the Secretary of State to compile of list of presidential primary candidates who are discussed in news media. They go on the ballot automatically. Michigan Secretary of State Ruth Johnson’s list omits former Virginia Governor Jim Gilmore, even though the Republican National Committee lists him as a bona fide Republican candidate. The Michigan Republican Party has the authority to add Gilmore to the list, but must do so by the end of the day, Tuesday, November 17. If the Michigan Republican Party doesn’t list him, he will need almost 11,000 signatures to get on the primary ballot. See this story.
Even if the Republican ballot ends up with only fourteen candidates, it will be the most crowded Republican presidential primary ballot in Michigan history. The previous record was twelve candidates, in 2012.
