true, but we can't afford to lose them all. Chaffee, Collins, Snowe, Spector. That's 4 senators, we can't afford to come out of this significant election with gains, only to lose 4 senators who switch parties.
and then let's not forget McCain and Hagel are still around.
Aside from the most vocal RINOs - Specter, Snowe, Collins, and Chafee - everyone has forgotten McCain, Warner, Murkowski, Stevens, Voinovich, Hagel, Lugar, Hatch...
