I can't believe some people are actually blaming Obama for this mess. Just look at the December and January job figures you numbnuts. Obama can't be expected to change everything in a month.
Well, the mere fact that the economy has deteriorated under Obama certainly doesn't demonstrate that he's responsible for the deterioration. Rather, it's his illiberal and increasingly reckless policies that make him share in the blame.
I expect him to be re-elected. Despite Obama's counterproductive measures (and destructive rhetoric), the economy will almost certainly recover by November of 2012. Obama will then be able to claim credit for the recovery that his policies hindered.
(Of course, the data that will be used to track economic performance—the unemployment rate, and particularly real GDP—are woefully inadequate. Even entirely wasteful government spending counts, for purposes of GDP, not as a transfer payment, but as "production." The predictable result is that as the government grows in size, the accuracy of real GDP and real GDP per capita, even as a crude approximation of living standards, becomes increasingly remote.)
