Holding The Center

Yuval Levin worries:

All these are moves in the right direction, and we ought to hope that if elected, Obama would stick to these new positions. But when he makes such moves so easily and shamelessly and then denies that he has changed at all, can we be blamed if we conclude he’s just playing us for suckers and will revert to his very liberal origins (as demonstrated by his very liberal voting record) if he becomes president?

But his list of Obama's apparent reversals is very thin gruel.
