Meanwhile, also from Vox, here's what President Trump is doing during the debates:
Thanks to a massive YouTube ad buy, the Trump campaign’s counterprogramming for the Democratic debate is probably going to reach more people on the site than the debate itself — though it probably won’t persuade many of them.
President Donald Trump’s reelection campaign has bought YouTube’s “masthead” — basically, the advertisement at the top of YouTube’s homepage — for Wednesday, the first night of the Democratic debates. That means anyone who goes to YouTube’s website is going to be hit with pro-Trump messaging. It’s an expensive move, and an effective one.
“It’s one of the highest impact digital ad placements possible,” Daniel Scarvalone, senior director of research and data at Democratic communications and strategy firm Bully Pulpit Interactive, said in an email.
