MSNBC and Fox call Texas for Clinton.

Remember, that's the popular vote in the primary. That accounts for 126 of the Texas delegates; 67 more are up for grabs in the caucus. The Texas primary has no bonus for getting an overall win. So with the margin this close, that's probably a tie in delegates -- even conceivable that Obama picks up more because of the way the apportionment works. But assume that's basically a wash. Then there's the caucus. People assume, though that's only based on earlier caucuses, that Obama will win there. So keep in mind the very distinct possibility, even a probability, that Obama will take more delegates out of Texas than Clinton, even assuming he narrowly loses the primary part of the contest.
