Neither one of the Clintons are examples of "progressive ideas." They're virtually indistinguishable from Republicans. That's why they couldn't win on their own. Obama won because he championed progressive ideas, and at least tried to deliver on them. Biden also won because he started making bold, progressive promises. His biggest problem now isn't that he can't deliver, it's that he's stopped trying at all. It's extremely clear that progressive ideas turn out voters. Your "math" misses the bigger point.
