Not every advertiser is bailing on Rush:

As Advertisers Flee Limbaugh, Pro-Gingrich SuperPAC Buys More Time

As advertisers continue to bail from “The Rush Limbaugh Show” after the host called a law student a “slut” and “prostitute,” the superPAC supporting GOP presidential candidate Newt Gingrich has essentially doubled down.

Gingrich himself has denounced Limbaugh’s remarks, but it hasn’t cooled the pro-Gingrich group Winning Our Future.

“Actually, we bought more,” Rick Tyler, a senior adviser for Winning Our Future, tells NPR. Tyler says the superPAC expanded its media buy for pro-Gingrich spots on the show because the conservative talk host “reaches more listeners who are likely primary voters in all the states than anybody else.”

Tyler declined to say how much was spent on the ads, but says they are a “big part” of a national media buy in Super Tuesday states. He says the ads will continue to run in such states as Kansas, Alabama and Mississippi, which hold their primaries next week.
