I doubt it. I still think Warren losing Bristol in 2018 had more to do with Baker being on the ballot.
It was also a product of Diehl's home-field advantage and Warren being the least popular elected official in the state.
By the way, I realize now I meant Plymouth, not Bristol in my original post.
But anyway, I don't expect his home turf advantage to help him much here this time around.
I'd think it would help more; local issues are more significant in state elections than in national elections.
Look at the maps for the other candidates in 2018; Orrall carried her House district and almost nowhere else and Brady, though she admittedly was closer than the rest of the Republican ticket everywhere, ran much closer than her running mates in Concord and Middlesex generally.
