The United States needs any viable third party. Unfortunately, the Republicrats have a lock on our political system, and the only way to get a viable third party is to change the rules about how we vote.

Specifically, first past the post voting provides a disincentive for third parties to compete because they are most likely to harm the candidate who is closest to their own position. Something like score voting, approval voting, or instant runoff voting is needed to break the deadlock.

Approval voting is probably the best bet because people who want to support a third party candidate could also vote for the first or second party who is closest to their position. It's simple, and much easier to support and understand than the other options. This would allow third parties to get a real sense of how well they are really performing before pushing their supporters to actually stop voting for the first and second party candidates.
