It appears Donald Trump crossed a red line this week when he attacked fellow GOP presidential candidate Ted Cruz as a "maniac" for taking on the establishment in Washington D.C.
"I don't think he has the right temperament. I don't think he's got the right judgment. When you look at the way he has dealt with the Senate, where he goes in there like a, you know, frankly, like a little bit of a maniac - you are never going to get things done that way," Trump said on Fox News Sunday.
Monday on his show, Rush Limbaugh questioned Trump's conservative credentials and said, "for any of you that are holding out hope that Trump is a genuine conservative, even in the Republican field, would not go after Cruz this way. That just raised a red flag for me."
Mark Levin, whose show airs later in the day, didn't hold back in going after Trump in defense of Cruz, but of all conservatives. Levin also slammed Trump for going after Supreme Court Justice Antonin Scalia.
"It was a bad few days for my friend, our friend Donald Trump in my view. I hope he learns from it. If he doesn't and stands firm and he keeps sticking it to conservatives and keeps promoting the establishment and promoting big government programs, it'll have an effect on him and you," Levin said.
"This has to be the dumbest strategy yet, defending the establishment," Levin continued abut Trump's Fox News Sunday interview. "Trashing Cruz? Look, there are things you can question Cruz about, his past position on immigration, his past position on trade, substantive, positions you can question him about. This is not that! You and I rally around him and have because of the way he's taken on the establishment, because of the establishment that Trump's taking on. So why raise a stupid issue?"
