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.
American government is based on the principle of majority rule. But in the U.S. Senate, a minority has turned that principle upside down. The filibuster rule, designed to protect the minority's right to be heard, has been transformed into a weapon that allows just 41 of 100 senators to squelch debate and block action on any bill, no matter its importance or public support.
