7. Dan Benishek (R-Mich.)
1st term (52 percent)
Benishek won in 2010 with a GOP wind at his back. He won't have that this year, but his bigger problem is that he hasn't ingratiated himself with voters during the past two years. Recent polls have shown Democrat Gary McDowell with a small edge but with a large number of undecided voters - not a promising sign for the incumbent. The race against McDowell is a rematch from 2010. While the district is conservative, it voted to send Democrat Bart Stupak to Congress for years. Right now, Benishek seems to be the slight underdog. But the race isn't over, yet.
Keep in mind that Benishek was tied early on to voting against funding for northern Michigan airports.
