It's an early exit poll, and we should obey all the important caveats about not trusting those, but since bloviation is the order of the hour, consider this from Marc Ambinder:
Who's to blame for the economy? Bankers (34%), Bush (29%), Obama (24%). Of those who blame bankers, Republicans hold an 11 point advantage.
If a majority of people who blame our poor economy on the banks are voting Republican, that's a major communications failure for the Democrats, whose attempts to reform the financial sector and hold it accountable was opposed by both the banks and the GOP. Since the passage of the Dodd-Frank financial-reform bill, the financial sector has been disproportionately supporting Republican candidates. If Democrats want to do better going forward, they need to present a clearer message about their efforts to hold Wall Street accountable, and that starts at the White House.
