Are you sure about that? I don't recall ever hearing Rush apologize for a statement. When he's been proven to be wrong, a VERY rare thing, he's issued corrections, but I don't recall ever hearing him apologize to stop losing advertisers.
What I do recall about lost advertisers is that when advertisers responded to coordinated smear campaigns against Rush by pulling their advertising, once they realized they had made a mistake and tried to reestablish business a business relationship with Rush's show, Rush has told the advertiser to take a flying leap.
