By 'wipeout' do you mean holding 5, 12, 13, 14, and 15 while losing 1, 7, and 9? Peters is a freshman elected in 2008 with 52%, this is a suburban district most likely affected by the tea party, and the PVI is only D +2; plus it's Michigan. Though the whole auto bailout probably plays well here.
Losing 3 CDs in one state is bad news no matter how you cut it. Probably shouldn't be described as a wipeout, but the MI Democrats are in bad shape.
This. Republicans will control the Governor's mansion in 2011. Looking at the state legislature, we'll also likely control the Senate, and have a good shot at the House. Michigan will certainly be a state Obama will have to work for in 2012, and who knows? I don't think it's out of the question to say Stabenow could be in trouble.
