Snowe to headline event with Massachusetts Sen. Scott Brown

U.S. Sen. Olympia Snowe has decided against stumping and raising money this election season for Charlie Summers, the Republican vying to replace her in the Senate.

But the retiring senator will stump for another New England Republican later this month when she headlines an event for Sen. Scott Brown of Massachusetts, who’s facing Democrat Elizabeth Warren as he runs for a full Senate term of his own.

Brown took Massachusetts’ political establishment by surprise in January 2010 when he defeated Democrat Martha Coakley in a special election to succeed the late Sen. Ted Kennedy.

Since then, he’s built a reputation as a moderate in the Senate who doesn’t stick to his party’s orthodoxy. A Bloomberg Government analysis of Senate votes recently found that Brown crossed party lines in 53 percent of cases since January 2011.

Brown scored second by that measure, trailing only Sen. Susan Collins of Maine. Snowe placed third on the list.

According to Brown’s campaign website, the event with Snowe is scheduled for Oct. 29, with additional details yet to be determined.

The Brown-Warren race is a close one, with the latest polling showing Warren with a single-digit lead.
