Just as an FYI, America First and The New America are also firmly against Biden as well, so if anything they’re allies to you.
Besides, if we focus on isolationism as you seem to be implying, it will just make things worse for us in the long run. Take the Great Depression for example. We went full isolationist during that time, and the Communist party thanks to FDR and his New Deal made inroads into America. You REALLY want a repeat of that?
