Somewhat surprised by the low ranking of Kennedy. The Cuban Missile Crisis alone ought to place him higher.
Sexcapades might be taking down his rating. Public attitudes toward reckless fornication by the rich and powerful have changed dramatically in the last few months.
Not to mention he has very little if any legislative accomplishments and he was the one that sent the first combat troops into Vietnam. I've said it before and I'll say it again, once the aurora of Camelot and the belief of "What would've/could've Been" fades, Kennedy's standing with the public and scholars will fall.
