Maybe New England, because it’s technically not Boston, and Patriots fans tend to be more conservative, than fans of the other Boston teams.
It’s not really Boston. Foxhuro was pretty even in it’s Political Presidential vote.
The Patriots are a possible, we did live up near Boston for 4 years (Hanscom AFB), and my son & family are still up there (Acton) — there are definitely conservatives strewn about but they keep a low profile.
