Listen closely to the Obama campaign's attack lines against Mitt Romney, and something has been missing lately. Gone are the charges of the expected GOP nominee as a flip-flopper, and in its place have been a barrage of attacks portraying him as the consummate plutocrat. It has served as a complement to the president's populist messaging and support for the Buffett Rule, casting himself as the defender of the middle class.
Two lessons to pick up from this: 1) Many Democratic strategists weren't sold on the effectiveness of the flip-flop charge because they worried that it unwittingly suggested a pragmatic side to Romney's politics, something that could be appealing to independents. Better to cast him as an arch-conservative capitalist than as someone who used to be moderate on certain issues. 2) Even though Obama has fundamental problems winning over working-class whites, his campaign appears to be going all-in on trying to capture enough of those votes against Romney, knowing it may be their best chance at threading the victory needle.
