I’m guessing that the average Bernie Bro would not be too offended by a Trump “Bernie is crazy” tweet. Perhaps it would be better to say that he’d be turned off by the tweet. He’d think less of Trump, and maybe take another look at traditional Democrats.
A possible 2020 vote flipped, for no good reason.
While I actually like Trump’s outspoken use of social media and his less conventional attitude towards the establishment, I do think it would be prudent to be a little less quick on the twitter button.
