From 1969 to 1977, Ed Koch served as a US Congressman from New York, and then as Mayor of New York City from 1978 to 1989. In 1982, he ran for Governor of New York but lost the primary to then-lieutenant governor Mario Cuomo. Let's say he managed to win in '82, and then went on to run for President at some point. What are his odds of even getting the Democratic nomination, let alone winning a General Election? And if he did somehow win, what would the US look like after President Ed Koch?
