(CNN) - Former Republican Sen. Scott Brown of Massachusetts dropped the 'MA' from his Twitter handle on Wednesday, further stoking speculation that he's open to running for a U.S. Senate seat in New Hampshire.
Brown has met a number of times with Republicans in New Hampshire, where he owns a vacation home, and when asked by reporters earlier this year if he would consider running for office in the state, he said, "I don't think I'm done with politics, but I'm not going to rule out anything right now because I really haven't thought a heck of a lot about it."
Brown's name change on Twitter (formerly @SenScottBrownMA; now @SenScottBrown) further stirs buzz that he might try to launch a GOP challenge to unseat incumbent New Hampshire Democrat Sen. Jeanne Shaheen in next year's election.
Brown is also considered a potential 2016 Republican presidential candidate, already having visited the Iowa State Fair, a sign the he might be looking ahead to the state that kicks off the presidential caucus and primary calendar.
Brown, who announced in August he would not run for governor of Massachusetts in 2014, was elected to the Senate in 2010 in a special election to fill the remainder of the term of left vacant the late Sen. Ted Kennedy. He was defeated in last November's election by Democratic challenger Elizabeth Warren.
New Hampshire television station WMUR first reported this story.
