From Chris Cillizza's column in the Washington Post:
New polling from the Washington Post and Bloomberg News suggests that the public — and independents in particular — see little difference between the effectiveness of the approaches of the two parties when it comes to the economy and don’t expect things will change much (if at all) if a Republican is elected in 2012.
Fully 45 percent of those tested said that if a Republican were president currently the economy would be about the same as it is. (Twenty three percent said it would be better; 25 percent said worse.)
Among independents, the number is even higher with 55 percent saying that a Republican president would make no real difference to the current state of the economy.
