People realize 'these morons' include millions of people who voted for Obama twice, right? 44 per cent of voters in 2016 were non-college whites. Those numbers are even higher in the rust belt states (including former Democrat strongholds) that cost Clinton the election: Michigan 54 per cent, Ohio 55, Wisconsin 58, Iowa 62.
The Democrats can't afford to write off that many voters. If Clinton had done as well with non-college whites as Obama, she would have won. It she'd matched Obama's historic highs with African American voters, she still would have lost.

It's foolish to fall into the trap of assuming that your most dedicated and passionate opponents are representative of everyone on the other side. Traditional and social media, animated by perverse incentives and algorithms, massively magnify the extremes. Most people are not hopelessly partisan or wild-eyed zealots. Most people are persuadable.
