Update: Homer in comments referred me to a Slate article about this, and it does indeed confirm the wild improbability of Hillary even knowing that Bill had done anything, consensual or nonconsensual, with Broadderick (assuming, for the sake of argument, that a sexual encounter did happen):
As I’ve written before, everything we know about the Clintons’ marriage tells us that Bill took pains to hide his affairs from his wife. In A Woman in Charge, Hillary’s biographer Carl Bernstein describes how Bill initially refused to settle a lawsuit with Paula Jones—setting off the events that led to impeachment—because he feared admitting a sexual encounter to Hillary. “Bill didn’t dare acknowledge to his wife that something had transpired with Jones, so he rolled the dice and risked his presidency on the outcome—just as he would when he denied for months that he had had a sexual relationship with Lewinsky,” Bernstein writes.
If Trump really does insist on going nuclear on the Broaddrick charges at Sunday night’s debate, I hope Hillary sticks closely to what she’s been accused of—greeting a woman who would later call her husband a rapist in what that woman interpreted as a menacing tone of voice. When you examine every accusation of Hillary as an “attacker” of women, it ends up looking equally flimsy. Claims that Hillary Clinton smeared Monica Lewinsky rest on the fact that, after learning of her husband’s dalliance, she called her a “narcissistic loony toon” in a private letter to a close friend. Some on the right think Trump should hit Clinton for representing, as a young lawyer, a poor man charged with raping a 12-year-old named Kathy Shelton. But the judge in the case had appointed her, and as the prosecutor in the case has recounted, she accepted only reluctantly. Bill Clinton’s history with women is hard to defend. Hillary Clinton’s history is not. And her own history is all she should be accountable for Sunday night.
