A bit of heresy on FP Was John F. Kennedy the flat-out absolute worst U.S. president of the 20th century? By Thomas E. Ricks JFK on coming into office not only OK'd the Bay of Pigs but then pulled air support at the last minute changing Langley's folly into one of their more notable mass suicide missions for dumb exiles. Things did not improve thereafter. Oddly JFK regularly tops POTUS popularity polls in the US. To be fair, like Barry, he spoke carefully crafted speeches well but I'd rate politicians on policy not spin. I can only put it down to him having much more important American qualities: a very rich daddy, good hair, a cute wife. It helps that Oswald arranged for him leave office before things really hit the fan leading to near canonization. Actually I think JFK is a fair bet for worst POTUS of all time. Neither Grant nor that other reckless East Coast blueblood Bush the younger came near to getting the Eastern Seaboard toasted.
