Thursday night, former president Bill Clinton was a guest on Piers Morgan Tonight with guest host Harvey Weinstein. Weinstein, the well-known Hollywood producer, openly acknowledged that he is a big supporter of both Clinton and Barack Obama, and he was working it for all he could. But it may have backfired. Writing in The Caucus, the politics blog of The New York Times, Michael Barbaro referred to Clinton’s comments as “an unusually open show of defiance against the party’s presidential nominee.”
