Michigan
Senator Debbie Stabenow- Hm. She's important to the FARM bill(Chairs the Agriculture Committee), but other than that, she's just a backbencher.
Senator Carl Levin- He Chairs the Armed Services Committee, and is quite an expert in that area. Far better than Stabenow, though he's still a liberal. He's pretty much a backbencher though, almost always in lockstep with his party.
Thaddeus McCotter- He's a pretty good legislator. He offers good solutions. I like him a lot actually. However, he backbenches, though he's pretty conservative. He was against SOPA, which I like. He's the most grandstander of the whole bunch though
