If you think Democrats are confident these voters will turn out, count how many times they urged viewers to “make a plan” to vote. An energized base doesn’t need that kind of encouragement.

Those efforts at base mobilization came at a cost. There was virtually no effort to win back the working-class voters who voted twice for Barack Obama but defected to Trump in 2016. The reason Trump is president today is because about one-third of the nearly 700 counties that twice voted for Obama went for Trump in 2016. According to Nate Cohn of the New York Times, Trump won because he “flipped millions of white working-class Obama supporters to his side.” If you were a working-class Obama-Trump voter watching this week’s convention, you heard a lot about gun violence, racial justice and climate change, but not much directed at you. The message you heard was: Democrats are not interested in your support.

That showed in Biden’s acceptance speech. It was in many ways an impassioned and effective address. But not a word about the opioid epidemic and deaths of despair that are destroying families. Not a word about the outsourcing of jobs that has decimated their communities. Not a word about confronting China, the country that unleashed covid-19 on our country and has decimated many economic sectors with unfair trade practices. Biden blamed Trump for the job losses from the pandemic. But these voters remember that before the pandemic hit, America had recovered a half-million manufacturing jobs under Trump after losing almost 200,000 factory jobs in the Obama-Biden years.
