You mean, blame the Palinbots, Akin or Conservatives if Romney fails to excite the base? We already have someone like that in the White House who blames ATM Machines, Bush and God...

In the eyes of his shriller, more spittle-fueled adherents and apologists hereabouts, Mittens is much like a cow wandering placidly through the streets of downtown Cairo: immune to any/all criticism and/or impediment by divine principle, if not an object of abject veneration outright.
The cow is holy. The cow is perfect. If the cow, for whatever reason(s) -- by whatever unguessable confluence of events, in the course of its dull, plodding amblings -- doesn't end up wherever the hell it was it wanted to go to in the first place: that's your fault, not the cow's.
