Republican Scott Brown's upset victory over Martha Coakley in Massachusetts could lead to the collapse of a healthcare bill, the Washington Post reports. Brown's election to fill the seat of the late senator Edward M. Kennedy (D) will reduce the Democratic majority in the Senate to 59 votes, just short of the 60 needed to break GOP filibusters. During his campaign, Brown pledged to help stop the healthcare overhaul, the Washington Post reports.
