"RINOs like Collins and Snowe and Spector cast plenty of votes for our side - we will get all three of those votes for Alito for example."
I wouldn't bet on ANY of those votes for Alito. Snowe has pledged to never vote for an anti-Roe justice to replace Sandra Day O'Connor.
Arlen voted for Thomas and Roberts. Arlen is a friend of Alito.
Arlen will vote for Alito.
