Reps. Mike Rogers and Dave Camp are giving a hand to their vulnerable in-state colleagues. The two Republicans hosted a Michigan Regaining our Majority Program event for Reps. Joe Knollenberg (R) and Tim Walberg (R) that raised $30,000 for each of them, according to the program.

Walberg has never had an easy fight for his seat. After losing a crowded 2004 primary to a moderate Republican, Walberg won the GOP primary in 2006 and defeated a little-known Democratic opponent by a small margin in the general election. Walberg faces state Sen. Mark Schauer (D) this November in the district, which leans Republican.

And for the first time in a few cycles, Knollenberg is facing a tough race this fall, against former state Lottery Commissioner Gary Peters (D). His district also has leaned Republican, but Knollenberg defeated a poorly funded opponent by only 6 points in 2006 and observers see him as vulnerable.
