Well, I don't agree that it was Romney who lost... Yes, as with any campaign it's easy to "Monday morning quarterback" and yes, Romney made mistakes... So did Obama...
Romney shouldn't have let the Obama camp get away with so much Bane Capital/rich guy early... They did the rope-a-dope... Bad move...
Obama shouldn't have let the Repubs repeat "failed stimulus" over and over and should have come prepared to debate in the 1st debate...
What it came down to was swing voters who just felt that Obama cared more about them and that Romney cared tom much about himself...
