Before I quit listening to Hannity, years ago, I found him to be the antithesis of free and open discussion of anything but his own omniscience as a political idiot savant.
I can't imagine why anyone would call in to his show.
He'd routinely take up 10 minutes or more of every hour telling listeners how they had to stay tuned because he had a terrific show for them today, and then every caller got 3 or 4 sentences in, in perfect agreement with him, before he'd tell them, "I'm up against the clock, Gotta Run," and hang up on them.
I gotta wonder if they're even real callers or Paid Voice Over actors.
