MA-02 Congressional district. Currently held by Richard E Neal – Democrat obviously. Voted for SCHIP expansion, against FISA reform, against funding Iraq war without surrender timeline, against border enforcement.
Typically runs D+11, ran unopposed in 2002 and 2004 (and possibly much further back). Opposed run by a Communist party member in 1988 garnered ~20% of the vote. Last held by a Republican in 1949. Mass GOP link, for what it’s worth.
