Background

Koster was originally elected as attorney general in 2008 as a Democrat after switching from the Republican Party. Koster won despite accusations that his campaign violated state law in raising money from multiple committees. He also survived the disclosure that he played a supporting role in a plagiarism episode that damaged Attorney General William L. Webster’s campaign for governor in 1992. Fresh out of law school, Koster worked for Webster, a Republican, as an assistant state attorney general. [1]

He defeated State Representative Margaret Donnelly in the Democratic primary for the nomination for Missouri Attorney General and won against Republican state senator Michael R. Gibbons in the general election, 53%-47%. [2] He was sworn in as attorney general on January 12, 2009, succeeding Jay Nixon, who had served since 1993.

Governor Jay Nixon won re-election by more than 12 percentage points, Senator Claire McCaskill won re-election by over 15 percentage points, and Clint Zweifel won by 5 percentage points.
