1 big thing: The live-streaming election

Former Rep. Beto O'Rourke, a hot Democratic prospect for 2020, posted a video of a dental cleaning to his Instagram story yesterday, a make-it-stop moment that showed how different 2020 will be online.

Elizabeth Warren joked during an Instagram live video, filmed in her kitchen on New Year’s Eve, that she drinks "Michelob Ultra — the club soda of beers."

Hillary Clinton learned that the hard way in 2015 when she used Snapchat to tell her followers that she was "just chillin' in Cedar Rapids." She instantly became a meme.

How they use it: Ocasio-Cortez makes mac and cheese while talking about her progressive platform or addressing her critics.
