Elizabeth Warren keeps calling Donald Trump a loser.

The Massachusetts senator just went on a tweetstorm to point out the different loser-y aspects of Trump, from his failed business ventures and sad insecurities to his blatant sexism and racism.

She then goes on to note that while Trump is a loser, he still poses a real threat—after all, she says, many of history’s worst authoritarians started out as losers. The only way to stop him? Make sure he stays true to character and loses the election.
