Remember when Kasich used to fill in for O’Reilly? This was not long after the Chandra Levy thing, either. I think Kasich started guest-hosting The O’Reilly Factor sometime in 2002 or 2003 and then FOX eventually gave him his own show, something like “Heartland with John Kasich” back in 2005/06. But Heartland got cancelled in April 2007.
He has done the Factor a couple of times recently.
