West Roxbury seems to vote overwhelmingly pro-life in Democrat primaries and races.
When was the last contested primary in West Roxbury? 1962?
Seriously, what do you mean when you say, "West Roxbury seems to vote overwhelmingly pro-life in Democrat primaries and races"?
There has not been a pro-life choice among the Democrats since Roe-v.-Wade at the presidential level, and at the city level, the machine annoints all the candidates.
