If I had to choose a party I would probably pick libertarian.
The problem is the two parties dominate the arena, and by participating in the voting charade it gives your consent to whoever wins. Win or lose you participated in the election process, so your consent is given.
The voting process has also been so corrupted that your vote isn't even guaranteed to go to your candidate pick, it could be stolen. So the fact that you voted is counted and used as a mandate for their corrupt agenda, just participating in a corrupt system at this point is enabling the corruption.
Also the two major parties push the same agenda, so lose lose for everyone involved.
