For what party?
You think the teabaggers are going to be crushed, or what?
You think the Republicans can throw away their 30+ year history of appealing to white resentment and the Democrats are going to roll over and let them take the Hispanic vote?
2020 is only 2 elections from now.
The national Republican brand is toxic. Things are similar to 1964, but worse, for them. They don't have a Nixon to save them this time.
People like O'Malley on the D side won't roll over for a Bush of any sort.
IOW, I don't see it.
YMMV.
Cheers,
Scott.
