Absolutely! Such nutcases call into C-Span every morning in droves.
But I'm very skeptical that any of them could confront Rush so calmly, elucidating their views in such an extremely cool and collected manner, never losing their temper and never sounding threatening — while at the same time putting forth the most absurd tenets of Left-wing ideology.

But if I'm wrong and if she's a real personality as opposed to an actress, then at the very minimum James Golden must have Lorraine's phone number in his Rolodex so that he can call her up for a few laughs whenever the show needs a change of pace.
