I personally think it's time for Trump to just get out of politics. He stirs up too many @$$holes on the fringes of BOTH parties and gives them a voice they otherwise wouldn't have. He also has this really weird affect on otherwise normal center left people, where they go bat$#it crazy whenever the guy does or says anything.
Personally, I'd like to see an guy like John Huntsman come back on the scene, and run with a moderate dem on the independent ticket.
