I am a Republican/Conservative, Regardless of that I (am) sympathetic of an 80 year old President, I am in my 60's and have arthritis as well as suffer with joint issues. My point being, Ya gotta know when to call it quits! Joe Biden should have threw in the towel YEARS ago. Just like Nancy Pelosi or several others I can name, (Left side OR Right side) He could be living very comfortably at his beach house with a Martini, OR whatever, maybe an Ice cream cone. What do these politicians stay in for? Time to Go home Joe !
