Good article. Yes, Vance was the "smooth operator," no doubt. Walz was the rougher [what's the opposite of operator? truth teller?]. It was disappointing, but Vance told so many lies that perhaps those who could identify the lies were not swayed by him. I wrote about what I considered to be his most heinous lies yesterday in Unmasking J.D. Vance: Exposing His Biggest Lies From Last Night .
By the way, I've mentioned your thought that Vance, by design, will become president quite soon after Trump wins the presidency, if Trump wins the presidency. Everybody I've mentioned it to was already thinking it might happen.
