Yeah, but she also had ~4% of the total possible endorsement points. And Biden only has 6 or 7%. (Also, Harris had almost no endorsements recently.) Empirically, it's the absolute share of party support that's predictive, much more than the relative one. That's the point.
That is to say, by far the most important conclusion from the endorsement data is that the party hasn't really decided yet (i.e. there have been relatively few endorsements). Probably the 2nd most important conclusion is that they're espeicallly lukewarm on all the non-Bidens.
And the 3rd most important conclusion is the only candidate with semi-OK endorsements *is* leading in the polls. The polls and endorsements tell a quite similar story in fact. They both point toward Biden being a fairly weak frontrunner, but no one else able to overtake him.
