BOSTON -- Republican state Rep. Daniel Winslow said Tuesday that he was forming an exploratory committee and was likely to be a candidate in a special election for the U.S. Senate seat formerly held by Secretary of State John Kerry.

Winslow, a former judge who was chief legal counsel for two years in the administration of former Gov. Mitt Romney, told reporters he was speaking with party activists, potential donors and others about the race. He gave no timetable for a definitive announcement.

"I'm about 99 percent there, but I need to make sure the Republicans in Massachusetts want me to take that step," he said.

The primary is scheduled for April 30, followed by the special election on June 25.

Two Democratic congressmen -- Edward Markey and Stephen Lynch -- are running for the Democratic nomination to replace Kerry, who left the Senate last week to become Secretary of State.

A native of western Massachusetts who now lives in Norfolk, Winslow, 54, was elected to the state House of Representatives in 2010 and reelected to a second term last year.

The Massachusetts GOP has been struggling to find a candidate since former U.S. Sen. Scott Brown announced on Friday that he would not run for Kerry's seat. Since then, several other high-profile Republicans, including former Gov. William Weld, former Lt. Gov. Kerry Healey and Romney's son, Tagg, have all said they would not be candidates.

Winslow has positioned himself as a fiscally conservative but socially moderate Republican who is pro-abortion rights and has been endorsed by the Gay and Lesbian Political Caucus.

While citing a "B" rating from the National Rifle Association, Winslow said he supported a discussion of ways to reduce gun violence, but would not immediately say if he supported reinstatement of a federal ban on assault weapons.

Winslow served as Romney's chief legal counsel from 2003-2005. He was asked if his past ties to Romney could be a potential negative in Massachusetts, where voters soundly rejected the former governor in favor of President Barack Obama in the last presidential election.

Candidates wishing to run in the Senate primary have only until Feb. 27 to gather the signatures of at least 10,000 registered voters. Winslow said he had no concerns about his ability to collect the signatures if he decides to run.
