From Wikipedia, the free encyclopedia John Russell "Russ" Carnahan (born July 10, 1958) is the U.S. Representative for Missouri's 3rd congressional district, serving since 2005. He is a member of the Democratic Party. The district includes the southern third of the city of St. Louis (known as South City) and most of the southern St. Louis suburbs including most of Jefferson County and all of Ste. Genevieve County. Some cities located in the district include: Webster Groves, Mehlville, Affton, and Oakville (as part of South St. Louis City), and the southern suburbs of Arnold, Herculaneum, Pevely, Crystal City, Barnhart, Imperial, and Festus, as well as Ste. Genevieve in the neighboring Ste. Genevieve County. Dramatic losses in population in St. Louis in the 2010 Census contributed to Missouri losing a Congressional seat effective 2013. In the proposed Republican created remapping of the state, Carnahan's 3rd district would mostly be absorbed by the Missouri's 1st congressional district. The move would place Carnahan and William Lacy Clay, Jr. in the same district.
