I would say Sanders is popular, and not just among "online people." He won Nevada, including a decisive victory among Hispanics. The state as a whole is a working class state, and Hispanics there especially so. While he's not more popular than Biden, but he represents the only other "lane" in the Democratic Party that has meaningful purchase with actual voters, especially "not online" voters. And of course, let's not forget that anti-Wall Street, anti-corporate sentiment is emergent on the right as well--especially among persuadable voters and independents.

What isn't popular among voters, by contrast, is the woke managerialism lane Warren has come to represent. That's significant both because it points to how the party should recalibrate its message, and also because of its implications for the party's management structure (where the woke managerialists have outsize power). I suspect Democrats' reshuffling of the primaries will significantly ameliorate both problems.
