Liberals may hate each other but they never stray far from the pack. Very few of them ever jump ship. And even when they do it's mostly for show. The most any of them ever do is have temper tantrums. They always come back to the fold.
I wouldn't count on the left dividing like the right is poised to do. It ain't gonna happen. If we can't take control of the Republican party we will be consigned to the wilderness. The best I can hope for is that the left sill so engorge themselves that they explode from their own excesses.
No matter what happens it's gonna be nasty to have to clean up...
The left won't and can't divide. They are tribal in nature, and their identities are consumed by the tribe. They are no Different than the Germans who believed themselves to be of superior Ayrian stock and therefore excused any and all of the atrocities of the third Reich as being ultimately for the "common good" ( of Ayrians anyway)
By not voting GOP we will fracture and kill the Republican party, and the Dems will become more emboldened. If we vote Republican, the Dems still do the same, and we get the kabuki theater of sociopathic liars pretending to be on our side and pretending to oppose the libs. Rubio is an excellent case in point. They will lie, cheat and steal till the Dems control everything. And then the system will implode as sure as Detroit.
In short, IDP is right. The point is Moot. Don't vote GOP- make sure as much blame as possible rests on the shoulders of the Dems and their F'd up ideology and hunker down. A Civil war it pretty much now inevitable. The libs won't back off. They cheated in the last election to the point where your were seeing MORE THAN 100% of the vote for Obama in some places, and will do it again in the next election. The IS no political solution. The old republic is dead. Who you vote for in the tawdry attempts to give the new regime legitimacy is irrelevant - voting is irrelevant, because they will get the result they want regardless, and make it known that is the case. We either fight them at our doors, our we accept the death of individual freedom and the last best hope for humanity. We may , of course loose, but I can't say I really wish to survive into the hell the Democrats will create. It will be worse than the USSR, and even as their chains are set upon them, the libs will scream "Its Bush's fault"
