Details of voting in congressional and state primary elections:
Voters must affiliate with a party to vote on that party's primary ballot.
If a party affiliated voter wants to change parties, they must do so three months before the primary election.
If you are an unaffiliated voter and want to register as a Democrat or Republican to vote in one of the party's primaries, you must complete a new voter registration form and your new affiliation is effective immediately.
Connecticut has a form of same day registration, but it is often a different location from the polling places.
