CNN’s Howard Kurtz invited NewsBuster Dan Riehl and liberal Daily Kos blogger Mike Stark on Sunday’s “Reliable Sources” to debate the recent attacks by the left on conservative radio station KSFO. As Riehl posted Saturday evening, Stark was rather cocky leading up to this debate stating at his own website that “CNN will want to hire me as a sanitation engineer because I will have mopped the floor with Mr. Riehl.”Well, the reality is that CNN might indeed want to hire Stark as a janitor, for he certainly didn’t come across as qualified to do much else as this video of the segment (provided courtesy of Ms Underestimated) clearly demonstrates.
