BOSTON -- Republican Scott Brown is crediting "the independent majority" with his win of the U.S. Senate seat held by the late Massachusetts Sen. Ted Kennedy.
Brown defeated once-favored Democrat Martha Coakley.
Brown will become the 41st Republican in the 100-member Senate, which denies Democrats a veto-proof majority. Democrats needed Coakley to win for a 60th vote to thwart Republican filibusters. The loss will make it exceedingly difficult for Democrats to push through health care reform legislation which has already cleared the Senate and House.
Brown will finish Kennedy's unexpired term, facing re-election in 2012.
Coakley called Brown conceding the race, and Obama talked to both Brown and Coakley, congratulating them on the race.
The Democrat said the president told her: "We can't win them all."
