Clinton has been showering late-night shows with good ratings for some time now, as part of her personal-charm offensive. Last month, the Dem frontrunner helped ABC’s Jimmy Kimmel beat CBS late-night host Stephen Colbert for the first time in total viewers and the demo. In October, she made her first visit to what she called “The Cathedral of Colbert” tonight, which made her the fifth White House hopeful to appear on Colbert’s show since his debut on CBS, goosing his ratings too. Colbert had been prepping for that moment since his first week as host of The Late Show in September, when he detailed Clinton’s carefully formulated plan to become more spontaneous and genuine coinciding with the start of her march through the late-night TV landscape. The Clinton Authenticity Campaign started in September, when the notoriously guarded politician stuck her toe into the late-night arena, playing Telephone with Pretend Donald Trump (aka Jimmy Fallon) on NBC’s The Tonight Show. She’s also appeared on NBC’s Saturday Night Live playing Val the bartender, who sang a duet with a power-hungry Hillary Clinton, played by SNL regular Kate McKinnon.
