The super PAC backing Treasurer Steve Grossman’s gubernatorial bid spent nearly $47,000 last month on polling and media production by former members of President Obama’s campaign team, signaling the outside group’s first foray into advertising.
The Massachusetts Forward Together Independent Expenditure Political Action Committee, run by Grossman neighbors who have avowed their support for his campaign, paid nearly $28,000 to Putnam Partners. Putnam is a Washington D.C.-based political advertising firm that worked for Obama in 2008 and 2012.
The super PAC also shelled out $19,000 to the Benenson Strategy Group, a New York-based polling firm run by Obama’s pollster, Joel Benenson.
Earlier in June, the group had spent $11,000 on research and fundraising.
As outside groups ramp up spending in the gubernatorial campaign, all three Democratic gubernatorial candidates -- Grossman, Attorney General Martha Coakley, and former federal health care administrator Donald Berwick -- have voiced support for state legislation that would require super PACs to report donors within seven days of their expenditures.
A Grossman spokeswoman said last week that he would urge any super PAC spending money on his behalf to disclose its donors.
Grossman’s campaign did not immediately respond to a request for comment.
