Change the election method to an instant runoff for President, U.S. Senate and House of Representatives.
Ballots are marked with the preference each voter has for each candidate.
Ballots are initially distributed based on each elector's first preference. If a candidate secures more than half of votes cast, that candidate wins. Otherwise, the candidate with the fewest votes is eliminated. Ballots assigned to eliminated candidates are recounted and assigned to one of the remaining candidates based on the next preference on each ballot. This process continues until one candidate wins by obtaining more than half the votes.
This will allow people to vote for someone other than a Democrat or Republican without feeling like they're throwing the election to one side or the other.
