Limbaugh reaches 0.01 percent of the US population. His promoters will give you a much higher number, but any person who listens to the entire show (and it is a show) is counted as a separate individual for each 15-minute segment -- if you listen to all three hours you are counted as 12 people! That's as accurate as much of his bellicose talk.
He recently said that he could stop the GOP candidates' campaign bickering by telling them to stop. What an ego. Aside from his vain and mean-spirited talk, he is really a nobody. Most of America is working during his airtime (12-3 EST), so has the time or inclination to listen?
Rush should change the spelling of his last name to LIMBO...for that's where he really is in the totality of political discussion, though he does make for good copy with his silliness.
