Looks like the “Lock” the MSM and pundents have been saying about GOP not being able to gain much in the Senate are vastly overstated... Taking 10 seats to take the majority is an uphill climb, but I don’t think its impossible. There is no doubt the GOP are going to take senate seats in ‘10, its just a question of how many of the 33 or so up for election they will gain.
5 or 6 seats would allow them to shut down the Senate any time they wanted when you remove Collins and Snowe’s ability to close debate.
