Kate McKinnon's Hillary impression is, in short, brilliant, dialing up the former Secretary of State's ambition with a surreal, maniacal fervour as she launched her 2015 campaign with a video. McKinnon's style is a lot more unhinged than Amy Poehler's, which is why it works. I mean, she's literally slapping her chin and singing "first female president, first female president, me-me-me-me-me."
