Mark Thane Voted Against His Own Party's Voters. My opponent, Rep. Mark Thane, was one of the seventeen. It’s a U.S. Senate race and Rep. Thane is one of dozens of legislators who signed a letter about it. The Bankhead letter is one data point, but it is a clear one. It shows Rep. Thane is willing to publicly organize against the outcome his own party’s voters chose, when leadership decided a different outcome would be more convenient.
