Chaos on the Republican National Convention floor, where a group of yelling men and women tried and failed to force a vote that might allow for an outcome other than Donald Trump as a candidate for president.

Video of the dramatic procedural protest belied its stodgy explanation. What happened, via CNN, is that the anti-Trump delegates requested a vote on the rules of the convention so that they might support a candidate—any candidate—other than Donald Trump. Two voice votes were taken—hence the yelling—and the rules were adopted. Finally, the anti-Trump delegates requested a roll call vote to individually count each vote, which the convention chairman denied on procedural grounds, saying that there were not enough signatures to compel the vote.

Delegations initially supporting the roll call vote reportedly included Minnesota, Iowa Washington, Colorado, DC, North Dakota, Alaska, Virginia, Utah, Maine and Wyoming, though the Trump campaign was apparently able to flip enough delegates to prevent the plan from coming to fruition. Though the convention chair declined to list the flip-floppers, DC Examiner’s Joel Gehrke reports they included delegates from Iowa, DC, Minnesota, and Maine.

In a surprising turn, CNN reports Trump’s team worked with the RNC to resecure the delegates, meaning someone on the Trump campaign actually bothered to learn how the convention works:

Trump aides and RNC staff worked to strip signatures from the submissions that would deny anti-Trump delegates the signatures they need for a vote. They also challenged the validity of various signatures, with some coming up invalid, and some came up invalid. The combined effort was enough to prevent a roll call vote.

Staffers could be seen fanning across the floor, pulling aside delegates and coordinating their counter-efforts, and top Trump delegate wrangler Rick Gates said he was confident they can repeat their success last week when the Rules Committee met and blocked efforts to unbind the delegates.

“Our goal is to destroy them,” Gates said.

Amidst the shouting and whistles and shaking fists, the Colorado delegation reportedly walked off the convention floor, led by a group that includes anti-Trump movement leader Kendal Unruh and Regina Thompson, Ted Cruz’s former state director who is also the executive director of a group called Free the Delegates.

North Dakota GOP Chair Gary Emineth also reportedly quit his position as state finance chair in protest.

A complex dance, to be sure. Here’s how it played out on TV: UNINTELLIGIBLE YELLING.
