Romney lost because voters saw no difference between Obama and Romney. Might as well keep the liberal you know as they say.
I was repeatedly informed by Team Mittens' self-appointed advocates on this very site, throughout the entirety of 2012, that:
a.) ... as a socon, my views and desires were "statistically insignificant" and "fringe," and therefore did not merit serious (or even grudging) consideration or inclusion; AND, simultaneously --
b.) ... as a socon, my lone, individual vote was absolutely essential, and the only sure thing standing between The Forces of Light and C'Thulhu's Ravening, Extra-Dimensional Night Hordes.
At no point whatsoever did the thundering cognitive dissonance absolutely inherent in those two violently antipodal viewpoints occur to any of them, however fleetingly.
So, obviously, then: they ended up blaming Mittens' epic electoral belly flop on voter fraud. ;)
