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.
That vote requires 60 Senators to agree to end debate. Often there is no filibuster of a Supreme Court nomination. In those cases, a debate is held on the nomination and then a vote is taken by the Senate. A majority of voting senators must approve the president's choice for the nominee to be confirmed.
