Fairness?

It took a court settlement but Clear Channel is holding back from outright free PR and radio time for candidates, which 98% of the time ended up being Republicans. What I wonder about is how often Jean Schmidt was on Willie Cunningham's program during the campaign. I thought I heard her on myself. Why was Paul Hackett not allowed to go on Springer's show then? I can see why he couldn't host Jerry's show, but was he not allowed to appear on it?
