President could help his VP win race, issue executive orders to cut student debt, or he could pardon his son Hunter

When Joe Biden finally ends his self-imposed seclusion at his vacation home in Rehoboth Beach, Delaware, this week he will emerge into a very different world than the one from which he isolated when diagnosed with Covid last Wednesday.
