Political career

Koster was first elected to the Missouri State Senate in 2004 as a Republican. He represented Missouri's 31st Senatorial District which consists of Cass, Johnson, Bates and Vernon counties.

Koster champions legislation for Truth in the Missouri Court System. Currently, Koster has a bill pending (SB55) for the elimination of paternity fraud.

On August 1, 2007, Koster made Missouri political history when he announced that he was leaving the Missouri Republican Party and becoming a Democrat. Citing his longstanding differences with the Republican Party on issues like stem cell research, workers’ rights, and the non-partisan court plan, Koster said that the Missouri Republican Party had become too beholden to the extreme right-wing to lead the state of Missouri forward. He commented, "Today, Republican moderates are all but extinct. He is the first high-profile elected official in Missouri ever to have taken such a leap.

Before his change of parties, Koster was Chairman of the Republican Caucus, the majority party's fourth-ranking position in the Missouri State Senate.
