However, it’s just possible that Trump has just enough influence that when he wants to be on, you let him on your show.
Oh and there’s this thing called RATINGS. People will tune in when you say “tonight Donald Trump will be on to discuss XXXXX” that might tune out if they say “tonight, Sarah Palin will be on to discuss XXXXX”.
What? They’ll all have Sarah Palin on of course.
She’s in a different league.
