A new Gallup poll shows Hillary Clinton leading nationally over Barack Obama 49% to 42%. It’s her first statistically significant lead since Super Tuesday.

Looks like that Rev. Wright story hurt. I don’t know if Democrats are shying away from Obama because some now believe he’s anti-American or because some now realize they’re on the verge of nominating a guy with a scant public record whom we simply do not know very well. Or maybe it’s a calculated move as voters decide Obama would be subject to harsh attacks in the general election (although I don’t think political calculation plays into significant poll shifts).

If these poll numbers hold or even widen, that would give cover to superdelegates who choose Clinton despite the fact she’ll likely trail in pledged delegates. This just keeps staying interesting, doesn’t it?
