I’ve learned that Mentzer Media Services, an East Coast-based media buying firm, is checking TV advertising rates and time availabilities around California. Mentzer has bought air time for many Republican governors and U.S. senators, and the Republican Governors Association. In the 2004 presidential election, Mentzer handled time buying for the two biggest conservative Republican “527″ committees, the Progress for America Voter Fund and Swift Boat Vets and POWs for Truth. Unlike political action committees regulated by the Federal Elections Commission and state agencies, a so-called 527 organization is governed by section 527 of the Internal Revenue Code. 527 committees do not fall within the regulatory realm of the Federal Election Commission and are not subject to the same limits as FEC-regulated PACs and state agencies. They are permitted to accept contributions in any amount from any source. This might be a move by as yet undisclosed Republicans to help battered Governor Arnold Schwarzenegger, who has begun a recovery in the polls but who faces the prospect of seeing two well-funded Democrats on TV between now and their June primary. His own re-election campaign is very low on money and the California Republican Party is not exactly flush, either. And this year, unlike last year, Schwarzeneggeer cannot raise money in huge six-figure chunks. Contributions to the gubernatorial campaigns from sources other than the candidate are limited to $22,300 each.
