San Antonio Mayor: Texas Going 'Purple,' Then 'Blue' San Antonio Mayor Julian Castro (D) on CBS's "Face The Nation" “In a couple of presidential cycles, you’ll be on election night, you’ll be announcing we’re calling the 38 electoral votes of Texas for the Democratic nominee for president. It’s changing. It’s going to become a purple state and then a blue state, because of the demographics, because of the population growth of folks from outside of Texas, and because, unfortunately, the Republican Party has gone so far to the right that they’re losing the business community. They’re losing the middle.”
