You can rank up to five candidates in order of preference, instead of choosing just one. If a candidate receives more than 50% of 1st-choice votes, they are the winner. If no candidate earns more than 50% of 1st-choice votes, then counting will continue in rounds. At the end of each round, the candidate with the fewest votes will be eliminated. If you ranked that candidate 1st, your vote will go to the next highest ranked candidate on your ballot. This process will continue until there are two candidates left. The candidate with the most votes wins.
