City Councilor John R. Connolly has a 7 point edge over State Representative Martin J. Walsh in the race to become Boston’s next mayor, according to a new poll.
The poll by Suffolk University for the Boston Herald found Connolly leading Walsh 41 percent to 34 percent, with 23 percent still undecided.
The survey of 600 likely voters was taken over five days from Oct. 2 to Oct. 6. It has a margin of error of plus or minus 4 percent.
On Sept. 18, less than a week before the 12-candidate preliminary election, Suffolk University released a poll showing Connolly leading the mayoral pack with 16 percent. Walsh was tied for second place with 12 percent.
The poll also did several head-to-head match ups and found Connolly leading Walsh 44 percent to 29 percent.
In the preliminary election, Walsh came in first with 18.5 percent of the vote, followed by Connolly with 17.2 percent. Both advanced to the final election Nov. 5.
The poll released Monday was the first of the final election and could have a significant impact on the race. Both Walsh and Connolly have been trying to woo political operatives and activists whose candidates failed to advance to the final election.Andrew Ryan can be reached at email@example.com Follow him on Twitter @globeandrewryan.
