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

The poll of 500 Boston voters likely to participate in the Sept. 9 preliminary election showed a wide gulf between Wu and Kraft, who drew 30 percent support to her 60 percent.

In a race where affordability issues have taken center stage, voters put housing and the economy and jobs at the top of their priorities list.
