We need to get rid of political parties altogether. The current two party system works for the powerful and wealthy to control the selection of candidates and who has a chance to win.  Our election system needs to be vastly improved.  The primaries is another hoop to jump through to control who gets in.  The electoral college is one as well.  The fact that there are no limits to how much money is used to buy elections doesn't help either.  Truth in political advertisements should be enforced.   Election day should be a national holiday like the 4th of July.  So many blocks to a working democracy.
Bernie Sanders is part of the solution not the problem.  The "Republicrats" are bought and paid for by multi billion dollar corporations, pure and simple and NOT working for We, the People.
