Montanans tend to like to have their Senators in the party who is in the majority so if they think the Dims will maintain control it will be Tester if they think the Gop will get control then Rehberg. I would not bet either way on the outcome but I think the absentee's and how they think the overall Senate race for control shapes up in the next few weeks will be the key...
I suspect that most MT people do not even know which party controls the U.S. Senate in numbers. I don’t think having a senator in the majority rings a bell with people, but I guess it could with some of the trendy independents.
