Souder was elected to the United States House of Representatives as a Republican in November 1994, defeating Coats' successor in Congress, Democrat Jill Long, in that year's national Republican landslide. He was re-elected in every election thereafter until his resignation in 2010. This is the only elected office he has ever held. He originally ran on a signed pledge with America that he would not serve more than two additional terms. He was regarded as a staunch advocate of abstinence education and family values.
