In a May 21 blog post, Politico's Dylan Byers noted the decline in Rush Limbaugh's ratings:

Rush Limbaugh took a significant ratings hit in some key radio markets last month in the wake of the Sandra Fluke controversy.

The conservative radio host's ratings fell 27 percent in the key 25-54 demo in New York City, 31 percent in Houston-Galveston, 40 percent in Seattle-Tacoma, and 35 percent in Jacksonville, according to a selection of the March 29-April 25 Arbitron ratings provided by an industry source.

Limbaugh's detractors attribute the losses to a rejection of the show following his controversial comments about the Georgetown law student.

“Clearly Sandra Fluke isn't the only one who didn't like Rush calling her a 'slut' given how many viewers that comment incinerated,” one radio insider said.

But defenders say that what looks like a decline actually represents a leveling out following increased attention from the controversy. In late March, Limbaugh boasted that his ratings had increased by as much as 60 percent in the month since he had called Fluke a “slut” and a “prostitute” on air.

A spokesperson for Limbaugh declined to comment.

Limbaugh, without offering any substantiation, bragged about increased ratings as recently as last Friday's show.
