We already know who will win -- Barack Obama.

After last night, the things we still don't know: how and when.

Not if, not whether, but how, and when.

Clinton won Pennsylvania. Congratulations. She was expected to win. After Barack Obama's worst month (Jeremiah Wright, Bitter, crappy debate, Media pile on) he managed to eat away a little bit at her lead from Ohio even though Pennsylvania was a stronger state for her than Ohio (Closed primary, Gov. Rendell, Mayor Nutter, family roots).

In short: Pennsylvania wasn't a game changer, and the campaign continues. The delegate math is pretty much unchanged, and that's really the only thing that matters.

I want this thing to be over just as much as anybody else; it makes me sick that we're going to have to listen to another few more weeks of this nonsense.

But let's remember: we're going to win. Our challenge now is figuring out how to beat Clinton as quickly as possible so we can turn to McCain.

We can afford to forget the math, because the math is over. We don't need to spin, because the spin won't change who is going to win.

All we need to do is remember: it's not if or whether. It's how and when.
