First, let me just say that the original post is factually inaccurate. Willey accused Clinton of kissing her, and Jones accused Clinton of exposing himself to her and propositioning her. Neither of these alleged incidents meet either the legal or the common definition of rape.
I'm skeptical of the "Media Research Center"'s methodology, and in particular I'm unsure why next-day network news stories are a good statistic for overall MSM coverage. It's also rather silly to include statistics on coverage of Clinton sexual allegations without including Monica Lewinsky (or for that matter Gennifer Flowers). MRC seems to be deliberately biasing their sample for propaganda effect.
Still, there does seem to be some disparity. However, I doubt much if any of it is due to racism or political bias:
-- Standards for how to cover alleged sexual misconduct have evolved
-- Cain is running for office. Jones story was public in 1994, well before Clinton's reelection campaign was heating up, and the other two stories were made public in Clinton's second term.
-- Clinton had a long history of accusations of sexual misconduct (some surely true, most certainly not), whereas Cain had never previously had any allegations made public.
And most importantly: The accusations against Cain were simply more credible than those against Clinton. Jones held a press conference in which she contradicted published information and accused Clinton of misconduct that she hadn't mentioned for years. Politico, a major news organization, announced in a story with multiple sources that multiple women had made contemporaneous complaints and successfully brought suit for Cain's alleged actions. Even if news organizations were inclined to believe Jones story, it would take them some time to check it out (thereby missing MRC's odd one-day deadline) whereas they could repeat Politico's well-sourced story on its own merits.
Indeed, all of the three women mentioned here had serious credibility issues (see, eg, Wikipedia):
- Jones civil case proved so weak that the judge threw it out in a summary judgment. While this was primarily because Jones failed to show damages, Jones had also damaged her credibility by, for example, being videotaped asking for factual prompts while telling her story.
- Willey repeatedly lied to the FBI
- Broaddrick filed a sworn affidavit saying that she had *not* been assaulted. Eventually, she made the claim that Clinton had assaulted her two decades earlier, but she had not made any contemporaneous complaint.
