YOUR PRIMARY VOTE MATTERS
Primary elections determine which candidates from each party will be on the ballot in the official election.
Some primaries are open elections (meaning you can vote for any candidate regardless of party), and others are closed (meaning you must vote by your registered party). Check your state’s rule here.
Make sure you are registered/eligible to vote in your state’s primaries here.
Be sure to register with an official party before primaries here.
