I dont think Obama actually said that. I believe that was Rush paraphrasing/summarizing Obamas remarks.
According to reports given to Major Garrett,
Obama Says His View on Taxes Prevailed Because 'I Won' , yes, he did. From his article:
............"Obama explained that lawmakers were closer together than the public realized on the stimulus package but warned of pitfalls if Congress and the White House don't work together. Again, according to participants in the meeting, Obama said this about rising above typical partisan differences:
"We're all political animals, we've all got political bases," the president is reported to have said. "If we don't get this done we (the Democrats) could lose seats and I could lose re-election. But we can't let people like Rush Limbaugh stall this. That's how things don't get done in this town."".............
