After the initial uproar, the Colorado and Iowa delegations walking out, the chair left the podium for 5 or 10 minutes. Meanwhile, there was a lot of lobbying happening apparently. The Chair came back, declared that three of the 9 states that had petitioned for a roll call vote on the rules—their chance to basically “vote their conscience” on Trump—had withdrawn their petitions, and the minimum number of states is six. Sen. Mike Lee of Utah disputes that. He says he heard there are 10 or 11 states with petitions, so there should still be enough states to order the roll call.
Unity!
