Donald Trump thinks we should "look into" an old allegation against Bill Clinton of rape. Joe Conason thinks that if we do, we should also "look into" an old allegation against Donald Trump of rape.
I must say that one of the weaselier tricks in Trump's arsenal is raising questions that others are supposedly asking. It's one thing to say "I believe Bill Clinton (or Hillary or Bernie or anyone) has done this awful thing and here's why I believe it…" That may be promoting a lie but at least you're taking responsibility for your own accusation. When you say, "Some people are saying this…I dunno…I'm just asking questions," that's real craven. And it's pretty irresponsible to try and spread a charge like that if you really and truly don't know anything about it.
