A Warren or Hillary ticket in 2016 will have a Hispanic in the #2 slot, not a white male. Democrats are not interested in the white male vote, it reliably goes about 70% Republican. Since they cannot run a “four more years” campaign promising to continue the Obama legacy, expect them to run another “be part of history” campaign as well as use a Hispanic on the ticket to ride the demographic wave.
A Bush/Christie or Romney/Bush or Bush/Huntsman campaign will not beat a Democrat ticket combining a radical white female and any Hispanic. Rubio or Cruz in the second slot of a RINO led Republican ticket will not help. The Republican Hispanic will get the Palin treatment by the media.
The only chance of a Republican victory in 2016 is a hard hitting “return to American values” campaign led by an unapologetic believer in individual liberty who is articulate, without scandal, unashamed, and able to talk directly to the people over the media. A gray haired country club wealthy white male (i.e. Bob Dole, Gerald Ford, John McCain, Mitt Romney) without strongly held beliefs will lose badly.
Personally I love that they are the front runners for the Dems. It's going to be a real challenge for the GOPe to find someone liberal enough to lose to them.
You said it all, brother.
I seriously doubt that the GOP will put forth a viable candidate.
