Also according to the Roll Call story mentioned below, Sen. Larry Craig (R-ID) says that he no longer supports the filibuster against the bill:

“They’ve had ample opportunity,” Craig said of the Republican dissenters who successfully rallied a majority of their Conference to block the bill last week. Craig added that he supports McConnell’s efforts to goad the conservatives into capitulating, saying that over the years “when I was in a minority position I was given fair fun, but I was never given carte blanche to kill something.”
