According to a recent poll, 74% of Republicans are worried about the deficit.
While that is indeed something that deserves worry, and it's certainly an issue that needs to be tackled, let us not forget that of these selfsame "conservatives," only 45% were worried about the deficit in December (when there was a Republican in office).
This is the same party whose most recent Vice President once stated "deficits don't matter."
Like Andrew Sullivan, I am glad to see fiscal conservatism return to the GOP, and amused by the timing of this moment of clarity. I wish I could believe that it was sincere, and not a knee-jerk partisan stance, but I need some evidence of bipartisanship, particularly in light of the Republican near-lockstep refusal to participate in the President's stimulus plan.
Calling for an investigation would be a good start.
