This morning, Karl Rove urged the RNC chair to warn candidates about participating in a Donald Trump-moderated GOP debate.
"Should a guy who's going to endorse be the impartial moderator of the debate?
More importantly, what the heck are the Republican candidates doing showing up at a debate with a guy who says 'I may run for president next year as an independent'?
I think the Republican National Chairman [Reince Priebus] ought to step in and say: We strongly discourage every candidate from appearing in a debate, moderated by somebody who's going to run for president.
Later, he warned the candidates again.
"It's going to be a giant ego trip, and anybody who thinks that Donald Trump is going to be the equivalent of Bret Baier or any of the other moderators we've had is kidding themselves."
