Former Massachusetts Senator Brown to kick off New Hampshire Senate run

Former Massachusetts Senator Scott Brown, who has been mulling a Senate run in New Hampshire for the past few months, plans formally to announce his campaign on Thursday, the Republican said in a letter to supporters on Monday. National Republican supporters have moved quickly to buy ads supporting Brown’s potential run against incumbent Democrat Jeanne Shaheen, seeing the race as an opportunity to shrink Democrats’ 55-43 majority in the upper chamber. Brown, who has focused much of his recent public statements on his opposition to President Barack Obama’s healthcare reform law, said in an e-mail to supporters that his weeks of canvassing the state convinced him that “you want a health care system that works for New Hampshire.” “Together, we can do all this, but it starts by changing leadership in Washington,” said Brown, who was a little-known Massachusetts state senator before he stunned the state’s Democratic party to win the U.S. Senate seat previously held by Edward M. Kennedy in 2010.
