On the Fact that (According to Kennedy Biographer, Michael O'Brien) Eleanor Roosevelt Once Said in December of 1958 that She Would Do All that She Possibly Could to Make Sure that the Democrats Didn't Nominate a Candidate (for President) Like John F. Kennedy (this in Response to a Question as to Whether She Would Prefer a Liberal Republican Like Rockefeller or a Conservative Democrat Like Kennedy)

So even Mrs. Roosevelt (along with "Look", "The Chicago Tribune", "Newsweek", "The Saturday Evening Post", etc.) perceived that JFK wasn't a progressive. Interesting (though, yes, the myth of JFK as some leftist gladiator will undoubtedly continue unabated WELL into the future).
