I flat out don't believe the Dr. Laura numbers. The only strong stations I could find in a (not exhaustive) check are KFI, KSFO, KEX, WJR, and WHO. In many markets she's on low-rated or non-rated stations like WSAI, and she's not present at all in many major markets.
Consider that WSAI is almost certainly her highest-rated affiliate in Ohio. Her second biggest affiliate would appear to be WCER in Canton.
I wonder if Mancow's numbers as shown still include WKQX in Chicago, and if he has only a fraction of that audience now. It appears 96.5 and an Indianapolis FM are his only big market stations with much potential. (In other big markets I noticed on his affiliate list he's on low-rated AM's). He was popular enough in Chicago I wouldn't be surprised if he gets back on the air there. WKQX's ratings collapsed after he left.
There may be some people on that list, and I'm betting Lionel is one of them, whose numbers mostly come from a single big-city station, WOR in his case.
