Obama dismal and catastrophic foreign policy was at most only tangential to the whole campaign, Hardly any ads were played about the Rats booing God or Obama’s commitment to gay marriage. These were considered not-PC and were left out. This is now the price we pay.
I think the conclusion has to be that Romney is politically inept, not out of a lack of intelligence, but because he's never treated running for office as more than a hobby, and has spent little time on refining his message, building grassroots support and figuring out the skills he needs in his political operatives. If the six years Romney had in semi-retirement (after ending his term as MA governor) to work out the kinks in his presidential quest weren't enough, even while his rivals were busy making a living doing other things, I have to wonder if he'll ever learn.
