The Montana Senatorial campaign of 2006 was the turning point for control of the United States Senate. Democrat Jon Tester won the seat over 3 term incumbent Republican Senator Conrad Burns when the DNRC spent massive amounts of cash on a very divisive campaign of attack ads and accusations against Burns that were later exposed as lies. Tester won with a very thin margin of victory, so thin that it was claimed by his friend, then Governor Sweitzer, that the victory was only achieved with a mathematically impossible 100% Democratic sweep of Montana’s 7 Indian tribal reservations.
