Dale Swenson's 16-year run as representative of south Wichita's 97th House District came to an end Tuesday night, when he was defeated by Republican Les Osterman.
Osterman won with 57 percent of the vote to Swenson's 43 percent.
Swenson served as a Republican during his first seven terms, but he switched to the Democratic party in January 2009.
When the two faced off in the 2000 House race, Osterman ran as a Democrat. Swenson beat Osterman 67 percent to 33 percent.
Osterman, 63, is a minister in the Church of God.
