FAQs: Voting in Primary Elections
YES. You do NOT have to register as a member of any party to vote in a Michigan Primary. We have an “Open” Primary. Any registered voter can vote in a Primary.
Yes, but you must choose all candidates from one party or the other in the Primary. As a Primary voter you will be given a ballot that has a column with the Republican candidates for various offices and a column with Democratic candidates for the same offices. The ballot will also have a third column for Nonpartisan offices such as judges and for Proposals. ALL voters can cast votes in the third column on nonpartisan candidates and proposals.
You cannot crossover (select partisan candidates from more than one party) in a Primary election. If you do, your votes for partisan candidates will be invalidated.
