I live here and replied to this post you linked. The TL;DR of the comment there is:

I do feel the lawsuit is valid, but the delays he’s complaining are caused by Republican efforts to make early/mail-in voting harder during COVID when they didn’t want people to easily vote in a hurry. Now that they do, they’re mad they got what they wanted.

It’s just more of them trying to “prove the system doesn’t work,” and the main proof they have is the stuff they themselves broke.
