Maybe JD Vance's eyeliner and fake beard are part of a disguise he's using temporarily while he lies his way through the campaign, and he's planning to change his identity after he and the so-called Donald Trump lose.
First minute of a rally for the so-called Donald Trump:
"Yay, his orangeness has finally arrived!"
Twelfth minute:
"Geez, this is boring as hell. Wanna go get a pizza or something?"
If the so-called Donald Trump were not just a CGI, they wouldn't be trying so hard to convince you it's real--doing things like putting the word "real" in his x-twitter handle.
