Ohio 16: Rep. Jim Renacci (R) vs. Rep. Betty Sutton (D)

In Ohio's most competitive House race, freshman Republican incumbent Jim Renacci beat three-term Democratic incumbent Betty Sutton. The merged district -- located in northeastern Ohio near, but not including, Cleveland, Akron, and Canton -- leaned Republican.

Tennessee 4: Rep. Scott DesJarlais (R) vs. Eric Stewart (D)

Republican physician Scott DesJarlais, who was elected to Congress in the Republican wave of 2010, won a second term despite the recent revelation that he had pressured a girlfriend to have an abortion a decade ago. DesJarlais was separated from his wife at the time.

Texas 23: Rep. Francisco Canseco (R) vs. Pete Gallego (D)

Republican Francisco "Quico" Canseco was one of several freshman members elected in the GOP wave of 2010 who lost in his bid for a second term. Canseco was a wealthy commercial real estate developer when he won his third bid for this seat two years ago, defeating Democratic incumbent Ciro Rodriguez. After a legal battle over the redistricting process, Canseco ended up with a district slightly more Democratic -- President Obama carried it in 2008 with 51%, according to the Cook Political Report. The winner was Democrat Pete Gallego, a state representative.

Utah 4: Rep. Jim Matheson (D) vs. Mia Love (R)

As Utah's only Democratic member of Congress, Jim Matheson beat his Republican opponent, Mia Love, the mayor of Saratoga Springs, who would have become the first female African-American Republican to serve in Congress.

Wisconsin 1: Rep. Paul Ryan (R) vs. Rob Zerban (D)

Being named Mitt Romney's vice presidential running mate did not affect Paul Ryan's chances at getting re-elected to the House. He won handily against Kenosha County Supervisor Rob Zerban.

Wisconsin 7: Rep. Sean Duffy (R) vs. Pat Kreitlow (D)

Rep. Sean Duffy was a former Ashland County district attorney and tea party favorite, but he was probably best known for his work as a professional lumberjack athlete and ESPN commentator and as a cast member on MTV's reality show "The Real World." He defeated a tough challenge from Pat Kreitlow, a former state senator and former local TV news anchor. Redistricting had given Duffy a more GOP-leaning district. He also enjoyed a financial advantage.
