First we need a viable 3rd party because if you drop your affiliation you can't vote in local elections which are very important. The tea party was started under Obama and he made damn sure that would never get off the ground. He used the IRS as his private Gestapo. Under Trump a 3rd party (call it what you want) can absolutely happen and should. Dems and (R) are the same party for the most part behind closed doors. We have the illusion of a 2 party system.
