Ok. It was February 2012 when John and Ken were suspended (and in my opinion, subsequently muzzled) for the whole Whitney Houston situation. See if you can pick a book before that and make an apples to apples comparison,both for J&K and the station as a whole as you have here. I bet they were doing a lot better then. That said, that is not the only difference between now and then, there are several other differences, a few I can list here:
1) Demographics - so many people that were J&K listeners have voted with their feet and taken residence in other states. The middle-class outflow from California (especially SoCal) is one of the most underreported local stories of the last 10 years.
2) Related to #1 - those same people largely voted Republican and in 2012 there was still some lingering hope amongst these listeners that sanity may one day come to Sacramento (J&K mostly rail about local and state issues, not too much national ones, at least for their pet causes) and J&K was their mouthpiece and spokesmen. With Democrats now enjoying a super-majority in the Legislature and sitting comfortably in the Governor's chair, their audience knows that J&K's railings no longer have any effect. They cannot shame, embarrass and harass local and state politicians to bend to their will like they once could.
3) KEIB - KEIB has only a fraction of the old KFI numbers, but those hard core conservative listeners (that still remain) are KFI's former core listeners who would tune in for hours from Handel and Rush in the morning, through Dr. Laura to J&K. That is a lot of TSL to let go. Now with Rush and Hannity both on KEIB, hard core conservatives have no reason to tune in KFI any more.
4) The overall talent level of KFI is simply not the same any more. Handel seems like a shell of his former self and the middayers just don't stack up. Therefore, J&K do not have the audience lead in numbers like they used to have.
In any case, the numbers comparison would be most interesting indeed.
