Yeah, I looked them up and they're all Dems.
Of course. It's Boston.
Does anybody run on the Republican line? Republicans in New York get a candidate...and sometimes he wins! 
No, it's a non-partisan race.
The last Republican to win a race of any kind in Boston was Althea Garrison in 1992, which is just flat out my favorite MA political story of all time.
Her opponent failed to return her signatures properly and was kicked from the ballot. The district was too apathetic to figure out the write-in campaign. And so, in arguably one of the most minority heavy districts in Boston, a Republican won an upset, narrow victory over no one.
But the best part, well... here's your el-oh-el moment:
followed up by a 54.9-45.1 loss in 1994. I'd have to check on Sunday to see which areas stayed with her. But a check of precinct results compared to one account of the minority population in the area suggests that African-Americans voted for Garrison in 1992.
Which should tell you how craptacular Irene Roman's campaign was.
Garrison lost 58/42 in a Dem primary in 1998 too
