MA Democratic machine. Although we're traditionally seen as a very liberal state there are many conservative parts of the state that could definitely be won by a Republican. Despite that all nine of our congressional districts go to the Democratic party making us the largest state to send their entire congressional delegation to one party.
In most cases these "conservative parts of the state" are skillfully coupled with much more liberal areas, so - no district is very likely to go Republican, except, may be, in very big Republican wave (a sort of Democratic gerrymandering).
