Two people write Trump’s tweets. He writes the angrier ones.

By David Robinson

Recently, political and digital analysts began to suspect that Donald Trump’s tweets are authored by two different people: Someone on his campaign staff is tweeting from an iPhone, and the billionaire himself is tweeting from his Samsung Galaxy. Some posts are markedly more hyperbolic and aggressive (“Like the worthless @NYDailyNews, looks like @politico will be going out of business. Bad reporting- no money, no cred!”) than the campaign boilerplate (“Thank you Windham, New Hampshire! #TrumpPence16 #MAGA”). In short, they sound like Trump. When Trump wishes the Olympic team good luck, it comes from an iPhone. When he’s insulting a rival, it usually comes from an Android.

My recent work has concerned text-mining and sentiment analysis, so I wanted to quantify the difference in Trump’s tweets. The data clearly shows that the Android and iPhone tweets are from different people, posting at different times of the day, and using hashtags, links and retweets in distinct ways. What’s more, the Android tweets are angrier and more negative, while the iPhone tweets tend to be benign announcements and pictures. This survey looks at 628 iPhone tweets and 762 Android tweets.

One consideration is what time of day the tweets occur, which we’d expect to be a signature of their author.
