A new poll of likely voters suggests that Boston Mayor Michelle Wu will smoke her principal challenger Josh Kraft in this fall’s election.

Wu holds a 30-point lead over Kraft with a little over a month to go before the Sept. 9 preliminary election, according to a Suffolk University/Boston Globe poll that was released on Monday.

The popular progressive first-term mayor is the preferred choice among 60% of respondents, with her top challenger, and fellow Democrat, Kraft, receiving 30%.

The two other candidates who have qualified to appear on the preliminary ballot, community activist Domingos DaRosa and former School Committee member Robert Cappucci, are far behind at just 3% and 1%, respectively, the poll found.

“Mayor Wu is in a strong position for reelection as we look toward the September preliminary,” David Paleologos, director of the Suffolk University Political Research Center, said in a statement.

Wu holds a strong favorability rating of 66% favorable versus 28% unfavorable among the 500 likely voters polled between July 13-16, with 65% of respondents approving of the job she is doing as mayor and 33% disapproving, the poll found.

Kraft, a son of the billionaire New England Patriots owner Robert Kraft and longtime philanthropist, was dealt another blow by that likely pool of voters — 61% of whom said Wu has had some challenges during her first term as mayor, but Kraft is not the answer.

While Wu holds a commanding lead, Paleologos said, “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 Schools.

But 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 preliminary turnout.

According to the poll, likely Boston voters are most concerned about housing (26%), the economy and jobs (17%), local response to the Trump administration’s initiatives (13%) and education (13%), heading into the preliminary, which will narrow the field down to two candidates for the November election.

Just 5% of likely voters listed crime — which Kraft has hammered Wu on — as the most important issue that will impact their vote in the mayoral race.

Half, or 50%, of poll respondents said bike lanes in Boston, another issue Kraft has lambasted Wu for, have made it slower and less convenient to get around.

But on ways to improve housing affordability, voters are more supportive of Wu’s strategy of using city funds to help finance stalled projects (28%), than Kraft’s, which is to roll back new affordable housing and green energy requirements that developers say increase the cost of construction (15%).
