Depends what the definition of sexism is.
Via The Examiner:
The Wall Street Journal reported on Friday that the Hillary Clinton for President campaign is preparing to deploy its most potent surrogate, none other than the candidate’s husband, former President Bill Clinton. Bill Clinton has all of the political skills and the ability to fake empathy that Hillary Clinton lacks. But, as CNN noted, Bill Clinton could be a double-edged sword. Donald Trump, the Republican front-runner, is already accusing the former president of “a penchant for sexism” for his long history of marital infidelity and alleged sex crimes, included a reported rape of a woman named Juanita Broddrick in the late 1970s.
Trump’s rhetorical gambit is an attempt to turn around Hillary Clinton’s attack on him for sexism for his statement that she had gotten “schlonged” in her previous attempt at the presidency in 2008. Trump is essentially accusing Hillary Clinton of being a hypocrite for remaining married to a man who humiliated her for decades with well-publicized affairs, including one with a young intern named Monica Lewinsky during his presidency. His alleged instances of sex crimes, which also included exposing himself to Paul Jones and sexually assaulting Kathleen Willey on the Oval Office, would have landed most people in prison.
The Clinton people are confident that they can deflect any attacks on Bill Clinton’s sordid sexual history, just as they did in the 1990s and that, besides, they do not think Trump will be the Republican nominee. But, Trump may be able to turn the issue to Hillary Clinton’s role as an enabler of her husband’s misconduct.
