You mean totally off-the-wall, over-the-top, completely lost their minds crazy? Doing insane, delusional and destructive things like claiming that America is pro-torture, that it's president started the war in Iraq for profit, undermining and exposing crucial intelligence and counter intelligence operations in a time of war, actively helping homicidal enemies of global civilization to "lawyer up," and that sort of thing?
Can you get crazier than that?
Yeah, they can start shooting people and blowing things up. I kid you not.
