Hillary Clinton is set to appear on the season premiere of Saturday Night Live alongside current Hillary impersonator Kate McKinnon this weekend. The fact that she turned down an opportunity to speak before the Human Rights Campaign, the country's most prominent LGBT organization, tells you how much of a priority this appearance is.
But it's not like Hillary hasn't appeared on SNL before. She did so during the 2008 campaign with Amy Poehler, who was then impersonating her. Fat lot of good that did her. So I don't see Hillary having a "sock it to me" moment like Richard Nixon did on the season premiere of Rowan & Martin's Laugh-In during the 1968 campaign (please see video posted below).
