All of the public data measuring voter preference in the 2017 Boston mayoral race show a gap in the low thirty point range, pointing toward a large victory by incumbent Marty Walsh over challenger City Councilor Tito Jackson on Tuesday, November 7.
There have been three publicly released polls of the race conducted by MassINC, Emerson, and Suffolk, all showing Walsh/Jackson margins in the 31 to 36 point range. The September 26 preliminary election showed a Walsh/Jackson margin of 33 points.

Walsh had a small victory over Jackson in Jackson’s own City Council District 7, winning 51% of the two-way Walsh/Jackson voters.
Given the consistency of the overall margin in the preliminary results and the polls, it would be a remarkable upset and an indication in some serious polling failures if Marty Walsh is not easily re-elected on November 7.
