I think you missed the "cigars for all" provision in a hidden sub-clause ...
An interesting sub-question, would the Harris VP nomination stand, or would the new presidential nominee get to re-Veep?
It stands unless they make her the nominee for president. Otherwise there is no vacancy for them to fill and the DNC vote holds. There is no provision to undo the vote.
Bernie would make the argument that he should be the nominee as the 2nd highest vote getter, but it's just an argument with no power inherent to it. That status may influence some of the public, but...
Harris would argue that just as she would take over had they been elected, so too should she under this circumstance. That argument, too, has no power inherent to it.
I think I'd recommend Bill Gates.
https://today.yougov.com/topics/politics/explore/public_figure/Bill_GatesI don't think Tony Fauci would take it, though if you told him it would help to save lives he might.
Sanders is the most popular, best known among the eligible political Dems, but I think his negatives are too high with too many. And Gates could handle the negative shit thrown at him more effectively than anybody else.
I'd rather not have to have the DNC make that decision, though, Really.
