CW says El Rushbo got ratings because he had Clinton to bash. Dubya comes along and his ratings are down. CW predicted when Obama got in, Rush's ratings would go back up when he once again had a target. They did not. Rush has never had a shortage of targets. Rush's act got old and tired. Rush forgot the prime adage of show biz: Always leave them wanting more.
The first part of that so-called CW is wrong. Rush already had ratings *before* there was a Bill Clinton. He took off during the first Bush Administration (when Rush was providing an outlet for a lot of conservative frustration over Bush 41's missteps) and his TV show which was also successful debuted before there was a Clinton (during the 92 campaign).
