The vote to end debate on the Dream Act and move to a final vote received only 55 votes, short of the 60 votes needed to overcome a Republican-led filibuster. Forty-one senators voted no. Three Republicans - Indiana's Dick Lugar, Utah's Bob Bennett and Alaska's Lisa Murkowski - were among the yes votes.
The procedural motion required 60 votes to pass, and Republicans had been dodging questions for days on how they would vote. If the senators who voted no had prevailed, the Senate wouldn't have been able to debate the package, let alone amend it and vote on it. There were some notable party splits. Two Democrats, Sens. Mark Pryor (Ark.) and Mark Begich (Alaska), joined the Republican filibuster effort.
