Bradley Barton is 41 years old. His father is U.S. Rep. Joe Barton. Bradley himself is a former candidate for Congress. Well, on Thursday at 4 p.m., he was arrested on a charge of driving while intoxicated with a child under age 15. He was busted in a school zone, outsideÂ Highland Park Middle School and McCulloch Intermediate School, in University Park. Now look. The man is entitled to his day in court. Maybe he wasn’t drunk. But the mugshots don’t look good.
