Rush Limbaugh's opponents are starting a radio campaign against him, seizing upon the conservative radio host's attack of the Georgetown law student as a "slut" to make a long-term effort aimed at weakening his business.
Media Matters for America is spending at least $100,000 for two advertisements that will run in eight cities where Limbaugh may be vulnerable, the Associated Press' David Bauder reports.
The ads use Limbaugh's own words about student Sandra Fluke, who told congressional Democrats that contraception should be paid for in health plans provided by private insurers.
Limbaugh, on his radio programs, suggested Fluke wanted to be paid to have sex, which made her a "slut" and a"prostitute." In return for the money, he said Fluke should post videos of herself having sex.
Under sharp criticism, Limbaugh later apologized. But Fluke declined to accept it.
Media Matters claims that 59 companies have specifically asked that their ads be excluded from Limbaugh's show.
