PA Doesn't Matter
Even as I sit here wasting time watching the votes get tallied, and it appears Senator Clinton's moribund campaign will limp along a bit further, I know in the end Jon Chait is right:
In general, I think the coverage of Pennsylvania is wildly overblown. What happens tonight is not going to effect the outcome of the nomination. Obama will be the nominee, and the only thing that could stop him would be a massive scandal. If Wright and Bittergate couldn't dent his standing, a loss in Pennsylvania won't, either. The only thing the Pennsylvania results could possibly change is the timing of Clinton's departure, and even that won't happen unless Obama somehow pulls off a shocker upset win.
The conventions and structural biases of journalism dictate that importance must be read into whatever outcome occurs, but the fact is, it really doesn't matter.
Part of why I've been relatively quiet the past few weeks, after jumping back into blogging, is that I got real excited about the primary election just before it started to get ugly, at which point I became a more solid Obama supporter and yet wanted nothing more to do with politics for the rest of my life. In the months since, both feelings have held pretty strong, though I think the latter will fade.
UPDATE: As Josh Marshall put it, status quo ante.
