Fred Barnes evaluates Obama's moving to the center:
Barack Obama's tack to the center is quite clever for three reasons (and maybe more, but three is all I could think of). One, it may cause moderate and centrist voters to feel more comfortable about voting for him. That's the big one. Two, he's better off being attacked by John McCain as a flip-flopper than as an unrepentant liberal. And three, he gave up practically nothing in the process. The tack to the middle has been mostly a fuzzy feint that didn't lock him into any new positions.
