This feud has gotten ridiculous. Republican front-runner and businessman Donald Trump is now threatening to boycott the upcoming GOP debate if host Fox News doesn’t remove Megyn Kelly as a moderator.

I don’t usually like the argument that takes the form of, “if candidate can’t stand up to X, how can they stand up to the Islamic State?” But I do wonder how Trump will be able to handle anyone as president if he can’t take the sort of pointed questions about his weaknesses that originally soured him on Kelly.

It all started last August at the first GOP debate, when Kelly asked Trump about the New York businessman’s comments toward women in the past. The question was one of the most memorable of the debate, and prompted Trump to later claim: “you could see there was blood coming out of her eyes … Blood coming out of her wherever.”
