Rep. Vicky Hartzler has won re-election over challenger Theresa Hensley in Missouri's 4th district.
Hartzler finished with 65 of the vote with 100% of precincts reporting. Hensley held just over 113,000 votes to Hartzler's more than 192,000. Hartzler beat Ike Skelton for the seat in 2010 but faced a difficult re-election bid after Missouri's U.S. House of Representative districts were redrawn.
Third-party candidates Thomas Holbrook and Greg Cowan had 3% and 1% of the votes respectively.
