re: If DeSantis wins in 2024 will some people still claim the election was rigged?

Ignoring for a minute that you're attempting to make some sort of point with a rhetorical question, "rigged" implies a foregone conclusion. Flooding areas with extra ballots and illegally harvesting them can give you an edge, and it did in 2020, but it's not absolute. A side can cheat like hell and still lose if the margin is big enough.

But what you're attempting to imply is that "rigged" vs "not rigged" is only a function of who wins or loses, which makes you sorta stupid. They'll cheat in 2024, no question, but it remains to be seen if it will be enough.
