I do think we could start to see Obama's harsh attacks start to backfire. If Romney can spin it as an attack on the American way, they can make Obama look like a sort of foreign entity that doesn't understand America.
I'll never understand why some people think that an informed criticism of aspects of our capitalist system is the equivalent of pure attacks on capitalism and America itself. Sure, Romney can spin the attacks as such and they might be effective, but we need to keep things in perspective. If Romney is making millions of dollars and still pays a lower tax rate than people with modest means, or if Bain Capital is responsible for sending thousands upon thousands of jobs offshore, then I don't think anybody has to simply accept that as the way things are. Sure they're not illegal, but that doesn't mean people have to assume that they're right or ethical.
