Two months ago, word was City Councilor Gary Rosen. was heavily considering a run for School Committee. He even indicated to one or two people that such a run was likely before deciding to mount a reelection campaign. Now, Rosen has begun posting signs around the city (the same ones he ran in 2007), that say “Councilor/Mayor.” So is Rosen really running for mayor again? Kind of. As Rosen puts it, anyone running for at-large councilor is still technically in the hunt for mayor until they submit a letter withdrawing their name. Thus, even Rick Rushton, who has repeatedly said he won’t run for mayor, is still in the race, strictly speaking. Rosen, anticipating the signs will get destroyed over the summer, says he is using them for now while he makes his final decision on whether or not he’ll run.
