So it’s no surprise that Washington took notice when after a tense interview with a Texas TV reporter on Monday, Obama unclipped his microphone with no smile in sight, and tersely warned, “Let me finish my answers next time we do an interview, all right?”
The president of the United States was not happy. Obama had been corrected (he lost Texas by 12 points, not “a few,” in 2008), he was accused of punishing the state for political reasons (he denied that the White House had any part in the decision not to award a space shuttle to Houston), and he was challenged with the most basic of political questions: Why are you so unpopular in Texas?
