For the second series of BBC Radio 4’s Why Do You Hate Me, disinformation and social media correspondent Marianna Spring heads to the USA. She investigates the social media backdrop to the presidential election, interrogating different online phenomena and cases of hate – looking at how they could potentially influence the way people vote.

Marianna travels from Colorado to Baltimore and New York, tracking down both those harmed and causing harm on social media. She investigates everything from extreme hate targeting officials and students, to online fandoms, deepfakes and corrosive conspiracy theories.

Over five episodes, she uncovers why people behave the way they do on social media during a heated presidential race. Each episode exposes the real-world consequences of what happens in this online world and its potential impact on society and democracy.
