The MA congressional districts are a bit of a mess, so I tried to form names around major cities and cultural centers.
MA-01: Springfield
MA-02: Worcester
MA-03: Lowell
MA-04: Tauton-Newton
MA-05: Framingham-Cambridge
MA-06: Essex
MA-07: Boston-Somerville
MA-08: Boston-Brockton
MA-09: Plymouth-Cape Cod
could be something like this:
MA-01 Berkshires (the the name springfield could be used for IL-13)
MA-02 Worcester
MA-03 Lowell and Lawrence
MA-04 Newton and Fall River
MA-05 Cambridge and Framingham
MA-06 Lynn, Salem and Peabody
MA-07 Boston and Chelsea
MA-08 South Boston and Quincy
MA-09 Cape Cod
