Rush' Loyal Listeners

The Daily Caller has an interview with Michael Harrison the founder and publisher of Talker Magazine, a talk radio industry publication. According to Harrison not enough listening data has been collected since the Fluke dust up but intuitively he thinks Rush Limbaugh's numbers are at a all time high. “The irony is that he probably right now has the biggest audience he’s had in years, and the double irony of all this is sponsors that are fleeing, they’re missing out on the best advertising buy in radio.” How does Harrison explain this? Loyal listeners. Sponsors ran out on him but his listeners stood by him.
