Jason Kander, a Democrat, is running against Republican Roy Blunt in Missouri. Kander is a lawyer, a former US Army intelligence officer, and Missouri’s Secretary of State. Kander was trailing Blunt, a long-serving establishment Republican, until he ran this ad. The Senate seat in MO is now very much in play.
