Walsh Tops Connolly By 7 In UMass Poll

State Rep. Marty Walsh has taken the lead over City Councilor John Connolly in the Boston mayoral race, according to a new poll out Wednesday.

Walsh leads Connolly 47 percent to 40 percent, the UMass-Amherst survey found.

It's the first poll of the race to show Walsh ahead of Connolly.

“No matter how you define ‘likely voters,’ our poll shows that Walsh has capitalized on a couple of strong weeks of campaigning to vault out in front as the clear leader in this race,” Brian Schaffner, the poll's director, said in a statement accompanying the survey.

Thirteen percent of likely voters remain undecided, UMass found. The election is Tuesday.

The poll, conducted Oct. 22-26 with 600 registered voters, has a 5.9 percent margin of error.
