This one is a little immature, but it's also extremely creative.
Your challenge is to have the most people with last names like Johnson and Cox and first names like Dick and Willie elected president with a PoD of January 1st, 1960.
Bonus points if you can make suggestive VPs.
Extra bonus points if you can do this without any presidential deaths or resignations.
Okay, I lied, this is extremely immature, but it makes you think if nothing else.
