A top-four primary or top-four ranked-choice voting is an election method using a nonpartisan blanket primary where up to four candidates, those with the most votes, advance from a first round of voting, regardless of the political party. The round two (general) election, held some weeks later, uses instant-runoff voting (IRV, also known as ranked-choice voting, RCV) to confirm a majority winner among the top set of candidates. One variation, called (FFV), allows five candidates to pass the open primary.
