37. I sincerely doubt Musk would swing the election to Trump in a scenario with an open Dem primary

Musk was certainly a factor in the disinformation rampant in social media, but all other things being equal we can't know who would have been the Dem nominee and how that may have changed the dynamic of the campaign.

IMO the SCOTUS immunity ruling was an enormous factor outside the Democratic Party. Jack Smith had to reformulate his prosecutorial case, and that delay may have been the difference between Trump in the White House or prison.

In any event, I think the Democrats were badly handicapped by not having an open primary.
