Republicans are such a perverted facsimile of what used to be a very reasonable party. If 6 years of Obama has taught us anything, it's that the empty can gets the grease. USA Politics desperately needs the GOP to fork into two factions - there are enough independents currently voting "D" to jump over to make a center-right candidate feasible. Center-right by US Standards, that is.
I'd say that's pretty self-evident - the last two presidents that ran on the Democratic ticket were both center-right candidates.
