Nick Beaudrot has your Texas primary results map. Basically, Clinton won the vast majority of the state’s land area, but Obama did well in the more densely populated areas and kept it close. Clinton, meanwhile, absolutely crushed him in the heavily Hispanic Rio Grande Valley areas.
Nick sees evidence in this that Democrats ought to be taking Rick Noriega’s chances against Rick Perry more seriously. I’ll believe a Democrat’s winning statewide in Texas when I see it, but I suppose crazier things have happened. Meanwhile, the growth of the Texas non-white population is kind of a looming timebomb for the GOP electoral college map. If Texas were to start voting like New Mexico, the Republicans would be in a world of pain.
