BOSTON (Reuters) - Former Senator Scott Brown has decided not to run in the June special election to fill John Kerry's former seat, the Washington Post reported on Friday, citing a Republican source familiar with Brown's plans.
Brown could not be reached for immediate comment. That decision would diminish Republicans' chances of picking up a traditionally Democratic seat and cutting into the Democrats' Senate majority.
Brown stunned the state's liberal establishment in 2010 when he won a special election to fill the seat held by the late Edward M. Kennedy, becoming Massachusetts's first Republican senator in three decades.
He left the Senate in January after he lost a re-election bid to Democrat Elizabeth Warren, a former Harvard professor.
