Hillary Clinton’s Twitter Chart of Doom

Polls had her winning. Prediction models had her winning. Financial markets had her winning. But Twitter had Hillary Clinton losing, with a steady downtrend in sentiment that foreshadowed her stunning defeat to Donald Trump on Election Day.

The 2016 campaign featured more than 300 million tweets mentioning Clinton or Trump, with the Republican commanding a dominant 2-to-1 share of that conversation. Both candidates faced unprecedented unfavorable ratings among voters, but sentiment on Twitter gave Trump an edge. From his June 16, 2015, campaign announcement through Election Day, tweets mentioning Trump were 51 percent positive (+1). That compares to 51 percent negative (-1) for Clinton since her announcement on April 12, 2015, according to data from social media analytics firm Brandwatch provided exclusively to Bloomberg Politics.
