Can a person vote for a republican candidate in the primary and then vote democrat in the presidential?

In Michigan, it is an open primary, and so anyone who is registered can secure republican or democratic ballot without changing or identifying party preference. Yes, in Michigan. Other states have different rules.

only some states allow a member from a registered party to vote for a candidate from a different party but if you live in a state that allows that, then Yes, you could vote for a republican in the primary and a democrat in the general election.

In CA, not without changing party affiliation. To vote in the republican primary you have to register as a republican. Independents can vote in the Dem primary without changing party affiliation.

In MI today...dems can vote Republican and vote Dem in the presidential.

In some states you have to vote within your registered party during the nominations, but you can vote for anyone in the General election.

So if you are a registered Republican, yes you can. If not, you may not, unless you live in one of the states that allows cross over independent votes.

In a primary, you can only vote if you are registered in that particular party. When it comes time to vote in the general election, you can vote any which way you choose.

Yes, provided you are a registered republican at the time of the primary.

Yes but you have to go to your town hall and change that you want to vote republican and then after you vote you must go back and switch back to democrat. That is the only way you can vote both.

Yes. You can vote for whomever you want to in the general election, regardless of your party affiliation or who you voted for in the primary.

Haha, are you really that scared? I am a Republican who enjoys horror movies and I am not afraid of Dems so far as to do what you speak of.

Of course.
