Specifically, sources with knowledge of the meeting say, the RNC chairman and his members want to settle on a strategy for convincing the networks to make two changes to their qualification guidelines: raising the cutoff percentage in polling, and using early-state polls instead of national ones.

There will also be continued discussion about the appropriate time to discontinue the undercard debates.

The meeting will take place at the Milwaukee Athletic Club, and will be attended by Priebus, his senior staff, and the 13 members of the RNC’s Debate Committee. Party officials stress that the proposed changes to be discussed can only be made with the consent of the networks, as campaign-finance laws prohibit the party from enforcing rules that could potentially help or hinder individual campaigns…

Still, it was the exclusion of Christie, one RNC official said, that troubled party officials most. Many felt he was among the strongest performers in the most recent Colorado debate, and he’s gained momentum since, with a WBUR poll of New Hampshire this week showing him in the thick of the race at 8 percent there. But Christie’s standing in that first-in-the-nation primary state doesn’t matter as long as networks insist on using national-polling data. The same is true for Jindal, who has steadily risen in Iowa polls over the past several months but remains mired at the bottom of nationwide surveys.
