Headed into the 2020 election, many Democrats and opponents of Trump have argued that the most important trait that anyone hoping to remove him from the Oval Office must possess is electability.

What that term means isn’t always clear, but in many cases, it has been interpreted as “able to win enough Trump supporters (especially white, working-class voters) to defeat Trump.” In short, that often means having the characteristics — white, male and moderate — that do not exacerbate the cultural and economic anxieties that led those individuals to back Trump.

The electability question is one of the reasons Biden has occupied the top spot in polls of Democratic presidential contenders since entering the race. The former senator is seen by many as the type of Democrat that former Trump supporters could get behind, and that’s a message Biden himself has been pushing. Biden has even gotten the attention of Trump, who according to many media reports believes that enough people who chose him last time could end up backing Biden and cause the president’s defeat.

But Harris has consistently pushed back on this idea.
