Why do you think I am a decline to state voter? However, this is a big but, the Constitution has that barrier for third parties, winner takes all. It was state of the art in 1789, but neither party will allow for proportional representation. They know that their parties would dissolve into at least three parties per national party.
Understanding how politics works matters. Righ now the kids who care for voters are in the midst of a revolt. We’ve been here before as well. The most recent was 1980, when the kids back then decided the donkeys needed to go the route you and I are not fond off.
Parties do change, and invert. The Rs have gone so far right, that this time it did not fully happen. Good luck with a third party that is successful. It can happen, but after the last time both have passed laws to make it near impossible.
