Publius has a very useful post about the highly arcane system Texas uses to allocate delegates. He claims that some aspects of this will help Obama; the safer conclusion is that polls of Texas are unlikely to be very helpful in determining how many delegates each candidate will win. (I'm also not sure that, given the total number of delegates at stake, that Clinton needs huge margins in Texas and Ohio to stay in the game; decent wins, it seems to me, would keep her in the game until Pennsylvania.) --Scott Lemieux
