A member of the Democratic Party, he was a U.S. Senator for nearly 36 years, making him the longest-serving Senator in Montana history.

Jon Tester
His election as President marked a transition for Montana Democrats as they moved into the majority leadership of the Senate for the first time in more than a decade. Term limits prohibited Tester from running for State Senate for a third consecutive term. Tester cited a prescription drug benefit program, reinstatement of the "Made in Montana" promotion program, a law to encourage renewable energy development, and his involvement with a bill that led to an historic increase in public school funding as accomplishments while in office.Tester announced his candidacy in May 2005 for the U.S. Senate seat held by Republican incumbent Senator Conrad Burns. Tester was the second Democrat to jump into the race, after state auditor John Morrison. While Tester was seen as having a greater following among his fellow legislators, his opponent, whose grandfather was governor of Nebraska, was able to raise significantly more money and had greater statewide name recognition.
