Texas’ percentage of whites with a college education isn’t in the top 10 among states, but it does have the highest among red leaning states. Texas looks like its 13th and you don’t hit another red state until 18th. The next highest red states are also all states where Trump is underperforming (Utah, Arizona, Georgia, Alaska).
