The Republicans might conceivably be able to take advantage, but they don't seem to have much appetite for it on the issues where it could make some difference (obvious example: TARP).  The reason, I suspect, is that they all voted for it.  Not that attacking something they've voted for -- or promoting their efforts on something they voted against, as with the stimulus -- is at all beyond them.  But it's a complicated argument that's pretty easily swatted down even by the miserable standards of the Democrats.

I could be wrong, though.
