just a hunch
I think it's over for Hillary Clinton. The Toyota Center in Houston is full of people who wanted to hear Obama speak tonight. Full. In Houston. In a concert setup, the center holds over 19,000. In Houston.
Of course, 5,000 showed up to see Bill Clinton at Lubbock High on Saturday afternoon. (Who knew there were 5,000 Democrats in Lubbock?)
My students voted last week on who they wanted our in-class debates to be between. Of course, their preferences for that aren't necessarily an indication of their actual voting preferences, but I don't attribute too high of a level of political sophistication to the kiddos, either. And on the Democratic side, in both classes, the vote was overwhelmingly for Obama.
Add the clear momentum with the fact that, due to the vagaries of Texas Democratic Party delegate distribution rules, heavily Hispanic districts that had low Democratic turnout in 2004 and 2006 have fewer delegates, I don't see how Hillary can win Texas. And if she can't win Texas, it's over.
I don't know. Maybe I'm wrong. But I think he's got it.
