With what McConnell has done in the senate, that is gone. Too many seats to defend and a complete crapping on the base.
The HOR will barely be republican but the GOPe could totally screw the pooch on that. Gerrymandering will only do so much both D and R.
POTUS could go R unless the GOPe keeps crapping on the base and on Trump. Then it is the democrat easily. Trump will go third party and I will give a **** YOU GOPe vote to him. The Uni-Party is going over the cliff whether at 140 or just 90 MPH. I say rip it open quick. There is a WHIG moment coming..or it might have already come for the republicans. If iJEB! is the candidate it's done.
