There continues to be a reasonable case that Biden has a comparative advantage in speaking to these voters. This article is anecdotal but it's not far off the polling data.
And really, shouldn't that be what Democrats are fundamentally about--speaking to and for the multiracial working class? Oh sure Democrats are about lots of other stuff too but this seems like an exceptionally important part of the package.
Don't get me wrong, I'm not sold on Biden. I see lots of problems with him as a candidate. But I do like that aspect of his persona.
"They are white and nonwhite alike, prefer Facebook over Twitter, if they are on social media at all, and can be hard to find at Democratic campaign events dominated by activists from the professional class. But these blue-collar voters could go a long way toward determining who captures the Democratic presidential nomination — and Joseph R. Biden Jr. is racing to press his advantage with that constituency....
But his greatest compensating advantage right now is notably durable support from a multiracial coalition of working-class voters who feel a kinship with the former vice president and believe he is the Democrats’ strongest general election prospect.
At fund-raisers and on campaign stops, Mr. Biden is warning his party against overlooking voters who were once a core Democratic constituency but had found some elements of President Trump’s message compelling in 2016. His campaign believes the Democratic Party risks narrowing its Electoral College path in 2020, and hurting its standing on Capitol Hill, if candidates do not appeal directly to these more moderate voters in battleground states in the Midwest and Sun Belt."
