Forget Massachusetts. Obama's problem is nationwide.

The New Republic reports:

If you believe some of the blogs, the Democrats lost Massachusetts, and Obama’s approval is plummeting nationwide, because he alienated his left-wing base. Perhaps that does account for an absence of turnout among young voters in the Virginia gubernatorial or Massachusetts Senate races, but the polls have not shown growing dissatisfaction among young, minority, or liberal voters--the three voting blocs that accounted for Obama’s strongest support in 2008. Where he has lost ground--and where the Democrats have lost ground--is primarily among white working and middle-class voters and senior citizens.
