Go Toomey!!
Although by 2010, the Republicans will be in a deep minority status in the Senate and primary voters will be less likely to risk their vote on a far-right wing candidate who would likely lose in the general.
Unless Obama wins and gives us the second term of Jimmy Carter he is promising and the GOP actually starts listening to its base, then Congressional Dems in both houses would have much to fear.
Then they can't actually label RINOS who they dupe in voting against their base to join with Democrats far right-wing and then run leftists who claim to be better moderates than their GOP opponents.
