I think Hillary will take the Presidency. Trump has damaged his brand even if he goes back to the middle and for Cruz or Rubio, the TeaBag philosophy is nowhere near mainstream. I don’t see the Senate Dems picking up 4 seats and the House Pubs would have to lose 30 seats - again not happening in 2016.
What may be interesting is if the moderate Pubs align with the Dems in a coalition or become independent/third party. I don’t see it happening unless TeaBaggers start losing but if they do then why go independent?
