The Republican National Convention broke into disarray today when Rep. Steve Womack of Arkansas, who was serving as the presiding chair, walked off the stage after ruling against a last-ditch effort by Never Trump forces to save their cause. The Never Trump delegates had demanded a roll call vote on the adoption of the convention rules, which they hoped to change in their Hail Mary effort to stop Donald Trump’s nomination.

Politico described the showdown:

The anti-Trump delegates opposed the rules and hoped to vote them down in the roll call vote. Their ultimate goal is to get a new set of rules that allow delegates to vote against Trump even if they are pledged to him based on the results of their state’s primary or caucus rules, though they appear unlikely to have the votes to do either.

Womack eventually returned to say that the group pushing for a vote on the rules did not have sufficient support after several states, which he didn’t name, withdrew from the effort.

Sen. Mike Lee, R-Utah, and former Virginia Attorney General Ken Cuccinelli led the protests of Womack’s decision to approve the rules on a simple voice vote rather than call for a roll call vote, and the Colorado delegation walked out of the proceedings entirely.
