I don't think that Pete Domenici will lose in NM. He doesn't raise the ire of the Dems here, and brings home the bacon for the National Labs and Military Bases. Finally, there is no challenger big enough to get decent traction. That seat will be at risk when he retires (probably after this next term)

I agree with you it is not a big risk for the Repubs, I think the biggest risk of a Repub lising their seat is in Maine. As someone pointed out earlier, Maine is becoming liberal, and so Repubs may have their backs to the wall.
