Hillary Clinton is tweeting more than Donald Trump and attacks him more often than he does her.

One of the major battlegrounds of the 2016 presidential election is Twitter, with both candidates slugging it out using 140 characters or fewer. Heather Evans, Kayla Brown, and Tiffany Wimberly have been studying both Hillary Clinton and Donald Trump’s tweets. They find that, in line with findings from previous studies on how women candidates tweet, in June Clinton out tweeted the Republican nominee, attacked him more often than he did her, and tweeted about political issues far more often.
