Except for Jack Kennedy in 1960. Yes he was liberal for his day...prepared to surrender Taiwan's channel islands to a really barbarian Maoist Red China to avoid confrontation (Qemoy and Matsu). Made up the fraudulent "missile gap" (which disappeared a short time after his election). Thought he could just sit down with Khrushchev and make peace but instead had his head handed to him (Vienna). Instituted the "Peace" Corps, which had the effect of radicalizing hordes of idiot American youth by sending them to turd world sh*t-holes and making them feel oh so guilty about what the eeevil Americans had done to these noble savages. Legitimized the regime of Castro for the next forty plus years. Allowed the USSR to build the Berlin wall and didn't even bother to come back from sailing at Hyannis Port when it began.
Just for the record, and those who don't know...
I nominate this for Post Of The Day!
