I'd submit that most anyone who understood the mewling marxist in 2008 played economic "duck and cover" the past 4 years.
If a "President Romney" enacts immediate business friendly reform and private tax relief along with government downsizing the American economy would resound with an Earth shattering boom in short order.
If romney behaves as a fiscal conservative and keeps his liberal social policies buried, where they should be, he would become an American hero.
Otherwise, there won't be anyone who will stand by him if he screws up like obama.
