The Koch brothers like to meet in secret with their political minions. And, for the most part, the minions prefer to keep their interactions with the billionaire campaign donors on the down low.

But not Chris Christie.

The governor of New Jersey, who currently chairs that Koch-tied Republican Governors Association, and who well understands that a steady flow of dark money will be required to light up his 2016 presidential prospects, is elbowing everyone else aside in his mad rush to defend the billionaire brothers.

A Koch favorite who has appeared at secret summits organized in the past by the major donors to conservative causes and the RGA, Christie has been among their most vocal defenders in recent months. At the the 2014 Conservative Political Action Conference, for instance, he hailed brothers Charles and David Koch as “great Americans who are creating great things in our country.”

Now, as the 2014 midterm elections approach, no one is championing the Kochs more aggressively than Christie—even if that means he has to grab the spotlight from candidates the embattled New Jerseyan is supposed to be assisting.

After The Nation revealed that Arizona Republican gubernatorial candidate Doug Ducey had flown to California in June to attend what was supposed to be a secret summit with the Kochs and the circle of millionaires and billionaires they work with to shape the political discourse, Ducey took a lot of hits at home.

Democratic gubernatorial nominee Fred DuVal demanded that Ducey to renounce the “dark money” support that has benefitted the Republican’s candidacy. DuVal campaign consultant Rodd McLeod offered a checklist of complaints: “Doug Ducey works for out-of-state billionaires, not for Arizona. He goes to meetings with them, gives a secret speech, says you’re known by the company you keep.”

Headlines in the state’s newspapers told the story:

Secretly kissing up to Kochs pays off for Doug Ducey

The “kissing up” piece, a column by The Arizona Republic’s Laurie Roberts, began

Well. I suppose it’s safe to say that Doug Ducey won’t be fighting the lords of darkness if he gets into the governor’s office.

Fresh off a primary in which dark-money attacks were launched against any Republican who stood in Ducey’s way, we now learn that Ducey has been cozying up to America’s premier princes of dark money.

As he traveled Arizona, Ducey was bombarded with questions from print and broadcast reporters about why he thought getting together with out-of-state oligarchs at an elite resort was—as the gubernatorial candidate told the Kochs—so “very inspirational.”

Those aren’t the sort of questions a candidate who is in a tight race wants to answer.

So Chris Christie did the answering for Ducey.

Visiting Arizona in his capacity as the chairman of the RGA, Christie was with Ducey when the gubernatorial candidate was asked about his sojourns with those premier princes of dark money.

Yet, though the questions were clearly directed at Ducey, Christie jumped in with the answers.

Such as they were.

Brahm Resnik, one of Arizona’s most prominent political reporters and the host of KPNX-TV’s Sunday Square Off, set the scene, explaining to viewers, “You’ll hear Christie jump in before Ducey could answer my question about why he meets in secret with the Koch brothers. Now, those brothers, Charles and David, are billionaire industrialists who host these beauty pageants for candidates for the benefit of their wealthy donors. Ducey’s campaign has benefited from several hundred thousand dollars from Koch-connected organizations—all the money from anonymous donors. Ducey is also supported by Sean Noble, an Arizona operative who is one of the leading bundlers of Koch brothers’ cash. Now, watch Ducey begin to answer my question a few minutes ago, before Christie jumps in:

DOUG DUCEY: Uh, uh…

CHRIS CHRISTIE: Well, that’s your opinion. Your opinion is that are that these folks are folks with dark money. The facts on Fred DuVal are pretty clear…

BRAHM RESNIK: You’re saying the Koch brothers and these entities are not dark-money givers?

CHRIS CHRISTIE: Listen, what I’m saying very clearly is that everyone has a right to participate in the political process and let’s judge these people up or down based on what they do. But, no, I don’t believe the Koch brothers are that—nor any of these other folks.

Christie dismissed attempts to track the influence of the Koch brothers as “silliness” and “sophistry.”

Ducey’s critics were taking the issue seriously, however.

The DuVal campaign featured links to the tape from the Koch summit, along with media coverage of it, on social media. A tagline read: “Doug Ducey is quietly hanging with billionaires who seem intent, among other things, on privatizing education, killing unions and eliminating government regulations that protect the air we breathe.”

As for the Ducey campaign, it wasn’t highlighting the Koch tape or the tape in which Chris Christie elbows Ducey aside in order to defend billionaires who have the resources and the connections to make or break ambitious Republican politicians like, well, Chris Christie.
