There's been a lot of Republican squawking about how Harris is a usurper or something because nobody voted for her, because she did not run for the nomination in the primaries.
But, consider: If Biden, having won the primaries, were to die -- nobody would suggest a new round of primaries was necessary. It would only mean the delegates pledged to vote for Biden at the nominating convention were no longer so pledged.
The situation that actually developed is no different.
Anyway, nothing in the Constitution obliges the parties to use primary elections -- those are a 20th-Century invention and are strictly a matter of party rules.
