Obama wins in SC, regaining momentum

With an extraordinarily huge victory, Barack Obama has taken back a measure of control over the Democratic race and now looks like a daunting foe for Clinton on Super Tuesday.

I think one particular statistic is important for both parties:

The exit polls showed the economy was the most important issue in the race. About one quarter picked health care. And only one in five said it was the war in Iraq, underscoring the extent to which the once-dominant issue has faded in the face of financial concerns.
If the war in Iraq is no longer an important issue on the left side of the aisle, that could spell trouble for the Democrats. That has been a sort of rallying point for the party over the past few years; if they no longer have that driving force to motivate voters, the general election could be quite difficult.
