Then expect Hillary to occupy the White Hut.
If there is not a real, viable candidate (conservative, tea partier, libertarian, WHATEVER) that Republicans can truly rally behind... this election will go the same way as when they fronted losing tickets ala Bush/Quayle '92, Dole/Kemp '96, McCain/Palin '08 and Romney/Ryan '12.
I expect if Rand Paul/Ted Cruz/Mike Lee and their allies keep pushing and pushing and pissing off the right people, there might be hope... but probably as a third party because the GOP/Rove Machine is defunct and without principle.
One bizzare twist, however, would be if the Bengazi crap has any sort of real ramifications and touches the Teflon Kenyan directly (it won't though)... I see Biden taking over, gun control really being rammed up our ass, he only lasts until the 2016 cycle, and because low information voters vote like it's a student council election then the Democrat ticket will be something akin to a Pelosi/Clinton 2016 ticket, handily voted in by the ignorant 50% of the population... much like 100+/- percent (most likely +) of the Negro vote went to 0bama. My advice is to buy land while it's cheap and interest rates hover around 0%, move away from any Blue or Blue-leaning state with big Blue pockmarks around metropolitain areas ("entitlement centers"), buy weapons, marry properly, and homeschool your kids to be pillars of local business and industry.
Maybe in 50 years things will settle out... Nazi Germany and the Soviet Union fell eventually... the whole of the EU is in process of collapsing... just wait it out in the woods and maybe in 2 generations we will have a viable federal government that is back to what the nation's founders intended.
The GOP's rapid extinction.
