What he does is irrelevant. The plaintiffs are suing to keep him off the Georgia ballot. If they win, then the State of Georgia may not print his name on ballots. No doubt he's going to lose Georgia anyway, but this will become a national story. Even his most avid supporters who believe his fable, will ask, "Why stay off the ballot? Why not just provide the documentation?" That's when the facade will begin to crumble.
Amongst reasonable people, his facade will start to crumble, but I can just hear it from his supporters.
Everything from “it shouldn’t matter, he shouldn’t have to show it” to “they didn’t ask any white guys for their birth certificates”.
Remember, they are all into cock-fighting and NASCAR down there.
