The question is, who's Biden's base? Not millennials, not Gen Xers.
Bernie has been raising money non-stop since 2015. He's got program. And Harris is raking in money and endorsements--she's 2nd after Sanders. Buttigieg is everywhere and is not about to let Biden take over his spotlight.
As Dovere notes: "The man who would become the oldest president in American history needs to get through a primary—one that’s already tracking 18 other candidates." All of whom have solid resumes and none of #Biden's baggage.
