Election denial isn’t the same thing as using an existing law on the books to interfere with appearing on the ballot, though. In fact, I’d say those are very different things.
I think the argument Aubrey is making is that if the GOP tries to keep Biden's name on the ballot after he steps down, or tries to stop the Dems from fielding any candidate at all, a substantial number of not-locked-down voters will find that repellent. I think that's a reasonable argument.
