PORTLAND — A Republican political action committee today began airing television advertisements in support of Democrat Cynthia Dill’s Senate campaign.

A group calling itself Maine Freedom has purchased air time on four Portland television stations to broadcast a commercial in support of Dill, a Maine senator who is the Democratic candidate vying for Sen. Olympia Snowe’s soon-to-be-vacant Senate seat.

Maine Freedom’s treasurer is listed as Michael G. Adams, a partner at the Washington, D.C.-based law firm Dinsmore. He serves as General Counsel for the Republican Governors Association, according to his corporate biography. Adams could not be reached for comment Friday.

Maine Freedom was created on Aug. 16, 2012, according to public documents from the Federal Election Commission.

The ad spot, titled “Feel Good,” juxtaposes former Gov. Angus King and Dill and concludes that Dill is the real Democrat, according to Janice Young, a sales assistant at WCSH 6.

Lance Dutson, campaign manager for Republican candidate Charlie Summers, was not aware of the advertisement when reached by the Bangor Daily News. “Our only comment on that is people are allowed to run whatever ads they want,” he said. “We’re focused on Charlie’s race and his message to get Washington’s fiscal house in order, and that’s what we’re focused on.”

The ad is scheduled to air on WCSH 6, WGME 13, WMTW 8, and WPFO 7 beginning today and continuing until Sept. 2, according to public files from WCSH and WGME.

Maine Freedom has spent a total of $71,560 to air its advertisement over the next 10 days, according to public files from WCSH 6. It spent $35,780 at WCSH, Portland’s NBC affiliate station, according to the order form. That represents 50 percent of the organization’s total ad buy. Maine Freedom spent $17,890 (25 percent) at WGME, the Portland CBS affiliate; $14,312 (20 percent) at WMTW, the Portland ABC affiliate station; and $3,578 (5 percent) at WPFO, the Portland Fox affiliate.

In Maine Freedom’s Statement of Organization, filed with the FEC on Aug. 16, Adams writes that, “This committee intends to make independent expenditures, and consistent with the U.S. Court of Appeals for the District of Columbia Circuit decision in SpeechNow v. FEC, it therefore intends to raise funds in unlimited amounts. This committee will not use those funds to make contributions, whether direct, in-kind, or via coordinated contributions, to federal candidates or committees.”
