Poll Shows Maura Healey With Big Lead In Democratic Primary Race For Governor

BOSTON (CBS) -- Attorney General Maura Healey holds a large lead in the race for governor among Democrats, according to a poll released Monday.

The survey of more than 500 registered voters from MassINC found that Healey has the support of 48% of Democratic primary voters, followed by state Sen. Sonia Chang-Diaz at 12% and Harvard professor Danielle Allen at 3%. The poll found that 30% still don't know who they'd support in the primary.

If Labor Secretary and former Boston Mayor Marty Walsh was running, he'd actually be leading Healey slightly with 32% of the vote compared to her 31%. But Walsh recently told CNN that he is not running for governor.

Healey is viewed favorably by 44% of voters surveyed, and unfavorably by 19%.

The poll also found that Republican Gov. Charlie Baker's endorsement could have an impact, if he decides to weigh in. Forty-two percent said they'd be more likely to support a Baker-endorsed Democratic candidate, while 29% said it would have the opposite effect.

Forty-five percent of voters said they want the next governor to be "about the same as Charlie Baker"; 26% said they want a governor who is more liberal, and 23% said they want someone who is more conservative than Baker.

In the race for attorney general, prospective candidate and former Boston City Councilor Andrea Campbell is leading with 31% in the Democratic primary. And though nearly two-thirds of voters don't have a favorite in the lieutenant governor primary, Salem Mayor Kim Driscoll leads the pack of Democrats with 10%.

On the Republican side, former state Rep. Geoff Diehl and Wrentham businessman Chris Doughty have announced their candidacies for governor.
