Boston Mayor Michelle Wu holds a commanding lead over three challengers in a new Suffolk University/Boston Globe poll taken of those very or somewhat likely to vote in September’s preliminary election.

Wu is the preferred choice among 60% of respondents, with top challenger Josh Kraft receiving 30%. Community advocate Domingos DaRosa receives 3% while Robert Cappucci gets 1%; about 7% of voters remain undecided.

Mayor Wu also holds a strong favorability rating (66% favorable vs. 28% unfavorable) and high job approvals, with 65% of respondents approving of the job she is doing as mayor and 33% disapproving. A total of 61% of respondents say Wu has had some challenges, but that Kraft is not the answer.

“Mayor Wu is in a strong position for re-election as we look toward the September preliminary,” said David Paleologos, director of the Suffolk University Political Research Center. “This poll also gives us some important insights into where her main challenger, Kraft, is edging her among certain sections of the electorate.”

Wu won by strong margins in nearly every demographic in the city, including union households, and respondents with students in the Boston Public School system. However, Kraft beat Wu 52%-38% among households who identified as having a member who works in public safety and 64%-28% among self-described conservatives, who make up a small part of the expected September turnout.

The poll, taken July 13-16, is part of Suffolk University’s CityView polling series. In 2021, the Suffolk University Political Research Center launched its groundbreaking CityView project, a first-of-its-kind series of public opinion polls focused on some of America’s largest cities, conducted in partnership with USA TODAY and major regional media outlets like WSVN-TV in Miami.

CityView polls investigate how urban residents feel about their overall quality of life and the top issues their cities are facing. In addition to Boston, SUPRC has conducted CityView polls in Seattle, Dallas, Louisville, Oklahoma City, Los Angeles, Detroit, Milwaukee, and Miami.

Top issues for Boston voters as they think about the upcoming mayoral election include housing (26%), economy/jobs (17%), followed by local response to Trump initiatives, and education (tied at 13%).

Highlighting concerns with housing affordability, 65% of poll respondents say the city should be allowed to impose a cap on rents or other forms of rent control.

A significant majority (62%) strongly support the Boston Trust Act, which prevents Boston police from detaining individuals solely based on immigration status, limiting local police cooperation with ICE unless the target has been involved in serious criminal activity.

At the same time, two-thirds of Boston voters (66%) say Boston police generally do a good job and treat people of different races fairly.

Half (50%) of poll respondents say bike lanes in Boston have made it slower and less convenient to get around, while just 18% say bike lanes have made it safer and easier.
