Even his criticisms on Biden are laced with attacks on Trump. Leibowitz doesn't hate Biden because he's a senile old fool who's not qualified to run a lemonade stand let alone the country. And he certainly doesn't hate him because he and his whole family are crooks who've been selling us out to China, throwing open our borders, compromising our national security, and getting us involved in more foreign wars. Leibowitz hates him because he's helping to usher in a second Trump term (and because his masters are telling him to).
