Democrat Martha Coakley, one of 10 hopefuls aiming to succeed Governor Deval Patrick, is the front-runner in both the Democratic primary and against Republican Charlie Baker, according to a new poll.
Among likely Democratic primary voters, she led the next closest Democratic candidate, Treasurer Steven Grossman, by 31 points, a new WBUR-FM survey conducted by The MassINC Polling Group found.
In a hypothetical general election for governor, Coakley topped Baker by 15 points, 41 percent to 26 percent.
In other head-to-head matchups, though, Baker ran ahead of Democrats Grossman, Donald Berwick, and Juliette Kayyem, who remain unknown by a vast swath of respondents, the poll found.
Meanwhile, Coakley, the state’s attorney general and 2010 Democratic nominee for a special US Senate election, is better known than any other candidate, according to the survey. Forty-nine percent of respondents had a favorable view of her, while 26 had an unfavorable view.
Thirty-one percent had a favorable view of Baker, the 2010 GOP nominee for governor and a former health insurance company executive, while 13 percent had an unfavorable view of him.
Twenty-three percent had a favorable view of Grossman, while 6 percent had an unfavorable view of him.
The three other Democratic candidates — Kayyem, a former homeland security official; Berwick, a former Medicare and Medicaid chief; and Joe Avellone, a biopharmaceutical executive — all had favorable and unfavorable ratings in the single digits, a sign that voters do not yet know who they are.
Independent candidates Jeffrey McCormick, a venture capital investor, and lawyer and former business executive Evan Falchuk also remain unknown, the poll found.
Also running, but not included in the poll, are Republican Mark R. Fisher and evangelical Christian pastor Scott Lively, an independent.
The survey polled 500 likely Massachusetts voters by landline and cellphone from March 14 to 16 and had a margin of error of plus or minus 4.4 percentage points. The question about the Democratic primary race was asked only of the 237 respondents who said they are more likely to vote in that party’s primary. It had a margin of error of plus or minus 6.4 percentage points.Joshua Miller can be reached at email@example.com. Follow him on Twitter @jm_bos.
