First Republican Jumps Into Race for Kerry's Seat Others publicly mulling a run By Kevin Spak, Newser User Posted Feb 8, 2013 9:35 AM CST 3 comments Comments Republican state Rep.

(AP Photo/Charles Krupa) (Newser) – After being rebuffed by Scott Brown, Tagg Romney, William Weld, and Kerry Healey, Massachusetts Republicans finally have at least one candidate for Senate. State Rep. Daniel Winslow, who had previously said that he was "99% certain" he'd run, yesterday told the Boston Globe he was "going to be 100% running for the US Senate." Winslow chipped in $100,000 of his own money to start the campaign, but that's a fraction of the $4 million to $6 million he estimates the venture will cost. Before becoming a state rep, Winslow served as chief legal counsel to Mitt Romney and as a district court judge. He'll fly to Washington on Monday to meet with the National Republican Senatorial Committee, presumably in the hopes of securing more funding. At least three other Republicans are also publicly considering runs, but every day they delay getting in will make that prospect harder, the Boston Herald points out, because candidates need 10,000 signatures by Feb. 27—and generally shoot for 20,000 in case some are challenged.
