In the aftermath of the 2016 US Presidential Election, we saw how social media can warp, manipulate and fracture democracy. 

Every political campaign sees its fair share of spin and misdirection, but campaigns and foreign groups challenged online ethics in a way never seen before.

Micro-targeting from Cambridge Analytics and Russian troll farms opened up the world's eyes to privacy and the power of social media feeds.

Questions were asked: What’s real? What’s not real?

Donald Trump’s campaign also took what Barack Obama did on Facebook in 2008 and transformed it in a way never seen before.

A Facebook executive claimed recently that the company was "responsible" for his election as president, not because of misinformation but because he ran the best digital ad campaign ever.

So with more people online like never before, what have we learned from 2016?

Mike Schmuhl, the campaign manager of one of the most unprecedented and unexpected presidential campaigns - Pete Buttigieg’s - speaks to 'States of Mind' about battling a presidential campaign online, the power of Donald Trump’s Twitter and misinformation.
