Faced with a diametric decision, Biden’s selection of Harris tells us his campaign has decided to focus on winning over non-voters. Non-voters are generally less white, younger and more likely to be women and favourable to Democrats.
Biden may bring in more white voters than Clinton anyway, given his background. Part of his appeal has long been his image as a “regular Joe” from a working-class upbringing. Where Barack Obama was sometimes viewed as aloof, Biden, his vice president, was seen by many as a link to the Democratic Party’s blue-collar roots.
