Theodore Roosevelt Said the Single Most Stupid Thing any President said. Now Joe Biden!

The promise not to run for a second full term made the great Theodore Roosevelt helpless through much of his 2nd term.
Joe Biden's saying he would consider a Republican as a running mate isn't that stupid only because he has never been as great as Theodore Roosevelt. He can't continue in the running for long.
Realistically, and not necessarily my preference, the winning team would be Bloomberg and Buttigieg. Otherwise, there is Bernie trying with all his might to elect Trump again.
