Being named Mitt Romney's vice presidential running mate has not affected Paul Ryan's chances at getting re-elected to the House. He is a safe bet for against Kenosha County Supervisor Rob Zerban.

Ryan has been asked multiple times whether he's hedging his bets by running for re-election while also running for vice president but the question is irrelevant. Ryan was tapped for the ticket after the deadline had passed to have his name removed from the House ballot. He's far from the first running mate to run for two jobs at once. Vice President Joe Biden was in the same position in 2008.

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

Rep. Sean Duffy was one of the higher-profile freshmen elected in the Republican wave of 2010. He 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." This year he faces a tough challenge from Pat Kreitlow, a former state senator and former local TV news anchor. Redistricting gave Duffy a more-GOP-leaning district. He also enjoys a financial advantage. Despite these advantages, this remains the most competitive House race in Wisconsin.
