The worst part about it is it's a smugness that isn't his. We've seen the dry, bland, nothingness of a person he actually is. He cowers behind MAGA to supply energy/cockiness he cannot produce himself, a gopher scared to stick his head out of his hole unless he feels that hot air
For me, it's the smug condescension that really takes Vance's repulsiveness as a public figure to another level
