Problem: Presidential politics is broken. Elections are negative and third party candidates have no chance. Candidates know that they can gain advantage by slandering their opponent. Because we can only vote for one candidate, it’s not enough to show your qualifications; you also have to destroy the opponents.
Solution: Approval Voting! Allow voters to vote for as many candidates as we want.
Benefits: Every candidate will try to win your vote. Campaigns would be positive and collaborative, rather than negative and combative. You can vote for several candidates if you think they would each be a good President. Voting for 3rd party candidates would no longer be a wasted vote. These candidates would finally have a chance, and would be able to run without fear of “stealing” votes from other candidates. Finally, winners of Presidential elections would have much more votes, giving the country far less partisanship, and a greater feeling of approval.
This would change the nature of Presidential politics — for the far better.
