Another primary nail-biter

I have a good feeling about today. Until recently the conventional wisdom was that Indiana would be close and North Carolina would be an overwhelming Obama win. Now most polls show Clinton ahead by a comfortable margin in Indiana, and within striking distance in North Carolina.

What if the unthinkable happens and she wins North Carolina? Surely at that point the superdelegates would no longer be able to avoid confronting the issue of Obama's serious weaknesses in the general election. This race may look very different tomorrow morning.

In national trends: Clinton has pulled ahead in Democratic voter preference. The latest electoral-vote map shows her defeating McCain easily, while an Obama-McCain match is too close to call.
