David Bernstein reports that Robert Fortes is jumping into the race for an at-large seat on the city council. Fortes is that rarest of Boston rarities - a black Republican - and joins Doug Bennett, the man from Nantucket, as a GOP standard-bearer this fall. Or rather, he would, if Boston had partisan elections, which it doesn't. Still, local Republicans haven't seen this much activity since John Sears retired as a city councilor back in the day, unless you count DINO Dapper O'Neil.
