Last week, Pete Buttigieg sat in a studio in Michigan, surrounded by 25 undecided voters who rushed, musical chairs style, to sit across a table from him and debate his positions on Kamala Harris and Donald Trump’s policies. Those on the perimeter raised red flags when they felt each debate had run its course.

It wasn’t a town hall or a cable news panel, and it didn’t air on CNN, Fox or MSNBC. Actually, the encounter didn’t air on television at all. Rather, it was the sixth episode of hit YouTube series “Surrounded,” from Jubilee Media, the independent L.A. production company behind other social experiments like “Middle Ground” and “Swipe or Swap.”

With episode titles like “Can 1 Woke Teen Survive 20 Trump Supporters?” and “Can 25 Liberal College Students Outsmart 1 Conservative?,” the series has gone viral since its September debut, racking up more than 50 million views on YouTube and dominating social media feeds.
