This past January, Massachusetts Senate candidate Scott Brown and Elizabeth Warren made a historic pact to call on third-party groups — like Super PACs — not to air television, web, or radio ads in their race.

But a mysterious new campaign organization may be violating the spirit of this agreement and is casting a light on the ultra-thin walls between Super PACs and candidate campaigns.

This week, a new Super PAC calling itself America 360 began spending money in the Massachusetts race to boost Brown and attack Warren. It released a very poorly-produced web video warning that “outside groups” were supporting Warren, amusingly listing web boards like Democratic Underground as these independent entities.

It dropped $197,340 on the race, funds which it told the Associated Press would be used “on social media, website videos and mailers.”

While all of this may not violate the letter of the Brown-Warren pact, one detail about the Super PAC possibly violates its spirit.

America 360 is as of yet staying hush on its donors and staff. Super PACs are required to reveal their donors, but this particular organization set itself up over the summer and didn’t spend anything until very recently — probably to avoid disclosure dates. There is a single $1,000 donation listed in its disclosures, from a company in Florida, which means that less than .5% of the group’s donors are public. America 360 can, of course, voluntarily disclose its donors early, but it has not taken this step.

One thing that we do know about America 360 is the identity of its spokeswoman, Alicia Preston. Preston is a public relations flack at “The Preston Group,” which does “strategic communications” for corporations and political candidates. Here’s the most interesting part about Alicia Preston: she’s a former Brown campaign staffer, as she describes on her firm’s website.

Super PACs and campaigns are barred by law from directly coordinating, but this is a prohibition that is difficult to enforce. But Preston’s presence in a Super PAC supporting Brown after he made a call for third party groups to dial down their interference in the election is suspicious, to say the least. Remember that the pact that Warren and Brown signed called on the two of them to in “good faith” try to stop the influence of outside third-party groups in the face. If Brown was acting in “good faith,” he’d be denouncing this outside effort by his former staffer.

I contacted the Federal Election Commission, and they told me that the next required filing deadline for Super PAC activity started on October 1st will be October 25th, meaning it will be at least fifteen days before we get a closer look at America 360’s donors.
