Summary
Republicans won a stunning upset in Massachusetts' Senate election, US news networks reported, dealing a potentially fatal blow to President Barack Obama's health care reforms. Republican Scott Brown pulled off the surprise victory in the historically Democratic state in a rebuke of Obama one year after he took office. With more than 80 percent of precincts reporting, Brown was ahead by five percentage points over his Democratic rival Martha Coakley. The lead meant it was impossible for Coakley to make up in the remaining ballots to be counted, US media reported.
