President Joe Biden tripped on a sandbag and fell on his face at the Air Force Academy graduation ceremony. We shouldn’t kick a man while he is down. But now he’s back on his feet, thanks to the special orthopedic “horseshoe” soles that stop him from falling over his own ankles. This president is a walking, talking, stumbling, rambling argument for the 25th Amendment, but let’s not kid ourselves. Only total incapacity or intervention from the donors can stop Biden from winning the Democratic nomination for 2024.
