You don’t have to register how you’ll vote, but in most states you have to register to say that you will vote. Depending on the state the rules are different. Sometimes you only have to register once per residence, sometimes you have to register for each election. And then there’s the whole “purging the voter rolls” silliness which some states use to try to exclude certain demographics from voting at all.
You have to be a registered Democrat/Republican to vote in their respective primaries, though, which is a little like registering how you’ll vote. It’s a pretty bizarre system, to say the least.
