A former campaign aide to Sen. Claire McCaskill has been hired as executive director of the Missouri Democratic Party.
The state party says Matthew Teter began his new role Tuesday. He'll replace Brian Zuzenak, who is leaving March 31 after a transition period.
Missouri Democrats have undergone a leadership change after losses in the 2010 elections. Former State Auditor Susan Montee took over as chairwoman of the party in December, replacing Craig Hosmer. Montee also is an ally of McCaskill.
Teter most recently worked as executive director of a nonprofit organization in Philadelphia that provides housing to people with AIDS.
He worked on McCaskill's unsuccessful 2004 campaign for governor. McCaskill won election to the U.S. Senate in 2006 and is up for re-election next year.
