If I was required to register for a party I wouldn't vote. Parties shouldn't even exist imo. I'm fine with voting across lines though because it may just be that people are fine with everybody running in their party and want to get someone closer to their political alignment in the other party. I'll admit though, it does suck that many use it as a tampering method. I'd like to see primaries done away with. Just put them all on the ballot and let everybody vote.It sucks that’s allowed to happen. States should only allow voting within party, or don’t belong to any party. Voting in the opposite party’s primary is the equivalent of election tampering IMO.
But yeah I'm not okay with being required to choose a party. Bernie is getting my vote because I don't see him as a Democrat but I'm really hoping he pulls the party in his direction. At this point he already has.
