Trump would beat all 3, no matter what media and pollsters say. The threat of China is an even bigger issue now, this is why Bidens advisers are telling him to give this "sort of, kind of sheepish, China is bad" shtick from time to time. Nobody is buying it and Trump will exploit Bidens own words, over and over. In the debate, it's going to be a trouncing. We all know it, let's not kid ourselves.
It's why when he played the video yesterday, the very first question the Canadian Daniel Dale, formerly of Toronto Star anwered, was the Biden response when he called Trump xenophobic for shutting down the border. He tried to tell the few CNN zombie viewers that Biden wasn't referring to the border closing, in fact, he didn't even know.
That is, on it's face, an inept and laughable explanation. You are the leading candidate for the Dem party and you don't know the border has been closed when all the other Dems AND media know? LOL. Put it this way, you better damn well know if you are the leading Dem candidate!
Cuomo has a career of politics behind him which leaves a great deal to be revealed and he isn't a broadly appealing politician. Cuban wouldn't answer the "China is bad" question from Jessie Waters, and, his NBA lineage would be a major weakness on this issue.
It's possible Trump loses, but only if there are some shenanigans. America First is FAR and away more popular with Americans. Dems are viewed as the China First/Illegal Immigrant First Party. That is major trouble for them, even Bernies Bros like Trumps stance against the Communists. Trump has that video of Biden raising his hand during the debates to give free healthcare to illegals. I'm sure that will go over well in the Rustbelt, along with their jobs that Obama oversaw being shipped out.
