Nah, that will never happen. For everyone that drops out of the system in protest, someone else will step in to take advantage of the void.
If we lose in 2012 we will just have to redouble our efforts. There really isn't any other choice.
The concern is that between demographic changes and an education system that teaches our kids pretty much nothing about free markets and what made America great, our people are perhaps more susceptible than ever to leftist, emotionally based feel good policies. If we continue losing the Hispanic vote at the rate we are, and continue marching towards imitating Europe, you won't even recognize what will pass as a "conservative" party. In Europe when the center right wins, it really means a party perhaps more liberal than our Democrats has been victorious. That, unfortunately, is the road we are on till one day the whole system implodes. When that happens the people around at that time will have an opportunity to relaunch conservatism, but we might not be around to see it.
A panic, a run on the banks and markets would demonstrate before the election that the productive sector is on strike. This is not a mere act of protest, it is a prudent action for those seeking to preserve some of their wealth. If, for some reason, a conservative Congress can effectively thwart zero, or there is a coup d’état, those missing the crash could swoop up the bargains if a recovery is expected.
