First off, Roosevelt built lasting programs. Second, he got us into a war to address the financial downside. Biden did not build lasting programs, he instead is continuing to tear down America. Will he get us into a war to complete that goal?
So FDR called the Japanese and begged them to attack Pearl Harbor?
The one area Biden might have surpassed FDR is in golf. He probably could have beaten FDR (but only after he got polio).
