Winding Down the Democratic Primary?

Now that Obama's won every contest since Super Tuesday, including states like Virginia and Wisconsin, I think he's got this thing won. Judging by his recent momentum and support in the polls, it's going to be impossible for Clinton to blow him out of the water in Texas and Ohio. If she can't win both of those states, or even if she wins, but by insignificant margins, she's done for.

Wisconsin wasn't even close.
