Yes, that seems to be the case. In part because things are just so badly broken, in part because Republicans have successfully obstructed, in part because Obama has had a more corporatist approach than a Democrat should (than anyone should). Republicans are behaving like winning the election is all that matters, by recognizing that the single best predictor of who will win is the economy.
I think you're right that there's a risk that the 2012 president might face a worse situation than Obama did.
Coincidentally, things got a lot worse for three years after 1929 crash until FDR was elected; if Bush had been president for three years after the 2008 crash, Republicans would get even more blame, just as Hoover did. Instead, this bad period has been under Obama taking office right after the crash.
