Republican campaigns agreed to take a larger role in negotiating the parameters of the upcoming presidential debates and largely cut the Republican National Committee out of the process during an unprecedented meeting of advisers for all but one campaign Sunday night. It was a signal that efforts from the RNC to alleviate long-simmering frustrations from the campaigns over the debates, which came to a boil last week after the debate hosted by CNBC—a sister channel of NBC News and MSNBC—had fallen short. On Sunday, the RNC told campaigns that it was appointing RNC Chief Operating Officer Sean Cairncross to assist with debate negotiations. On Friday, the committee announced that it would suspend the next debate hosted by NBC News and Telemundo over the way the CNBC debate played out, which campaigns have complained was poorly moderated and intended more to bruise the candidates than enlighten the voters.

Lindsey Graham's campaign manager, Christian Ferry, called dinner meeting of representatives of the Republican presidential campaigns "an extremely productive evening." There is a starting point for the GOP operatives—"we agreed that we would like the campaigns to negotiate with the networks on format going forward," Ferry said, and "continue to have the RNC help with logistics." According to Ben Carson's campaign manager. Barry Bennett, the campaigns all agreed to circulate a questionnaire to the networks hosting the debates asking for details on their planned formats, the moderators and how long the debates will go, among other details. The campaigns will hold a conference call before each debate to hammer out the details on a case-by-case basis, during which, Bennett said, he expects other issues of contention—like whether to hold an undercard debate and how to get more candidates involved in the main debate—to be ironed out.

All campaigns agreed that they want to limit the debates to two hours, allow each candidate to get 30 seconds for opening and closing statements, have final approval of on-screen graphics and figure out a way for the candidates to get more equal speaking time. Bennett said the issue of whether or how to hold an undercard debate is left to the individual broadcaster and will be discussed on a case-by-case basis with the networks. He indicated that the that bigger campaigns would be calling the shots, warning that they could boycott the debates if their demands aren't met. "A couple of us are the ones that are generating the ratings for these debates—if we don't come, that's a big bargaining chip," he said. Before the meeting, Bennett had floated the possibility of taking television networks out of the equation altogether and broadcasting the events online in partnership with Google or Facebook. He also suggested "varying formats" for upcoming debates, but said there was no agreement on what that meant. "It's really hard to get 15 people to agree to a particular format. But I would hope, from the Carson campaign's perspective, that they could be a little more creative than they have been," he said. Afterward, Carson told reporters during a stop in Panama City, Florida, that the meeting "marked progress."

"I think there's general agreement that the last debate was a farce and that something needs to be done about it," he said. "It's a waste of everyone's time when you do it that way, and sometimes things have to get pretty bad before people take action." But aside from the agreement to take a greater role in the process, little consensus on specific details came out of the meeting, and one key issue of contention—whether to reinstate the NBC News-Telemundo debate—remains. Sources within the room say Jeb Bush's campaign pushed to reinstate the debate, which is the only one being held with a Spanish-language outlet as a host, but Donald Trump's campaign manager, Corey Lewandowski, pushed back, threatening to boycott if it is reinstated. The meeting had been long in the making. The RNC decided before the presidential cycle began to take more control over the debates to avoid the long slog of bruising primary debates that many believe weakened eventual nominee Mitt Romney during the 2012 cycle. But the decision by the campaigns to wrench more control from the RNC suggests that effort backfired. Attendees at the meeting emphasized that the RNC will, however, continue to have a role in hammering out disagreements between the networks and the campaigns and making logistical arrangements and that it will still be involved in the negotiations. Ben Ginsberg, the GOP lawyer who moderated the discussion, said that the decision by the campaigns to take control over the process from the RNC marked a "course correction." The campaigns, he said, "all want a greater transparency and accountability in the way the debate process is working." One complaint, Bennett said, is that campaigns aren't given enough of a heads-up on the plans for each debate, making it difficult to schedule prep time.
