You are very correct.
We need more "R" in office to make the Snows and Specters very disposable.
With a filibuster proof majority, the RINO's have less power. (they may even jump ship ala jeffords)
R's voting against cloture were Campbell (CO), Collins (ME), Chafee (RI), McCain (AZ), Snowe (ME), and Sununu (NH). D's voting for cloture were Ben Nelson (NE), Byrd (WV), and Miller (GA).
