Barbara Jordan's 1976 keynote speech was well-delivered, but it had no significance other than that she was the first black woman to be a keynoter.
Cuomo's convention speech was a great speech (although it was false as anything and I frankly hated it). His 1984 speech at Notre Dame on abortion was pure claptrap.
Reagan's Challenger speech was rated highest of his speeches because it wasn't ideological in nature. His D-Day speech was way too far down. His "Tear Down This Wall" speech, as someone else noted, should have been in the top 5.
The "Checkers" speech was memorable, but it was by no means worthy of being ranked in the top 10. If I was to choose a Nixon speech it would have been his convention speech in 1968.
Hillary Clinton's "abort 'em all" speech at the Women's Conference was listed as a sop to feminism. She hasn't given a good speech in her life. I can think of half a dozen Bubba speeches that were far more memorable than anything Hillary said.
Maw Richards' speech ("poor George, he can't hep it") was nothing more than poorly argued invective.
Teddy Kennedy's best speech was his one at the 1980 Democratic convention. Why it's lower than his others is beyond me.
As far as acceptance speeches go, Goldwater's is underrated, because it's clear they take into account future significance and Goldwater launched the movement that led to Reagan. Jerry Ford's acceptance speech was the best of his life, but probably not listed because he lost.
Anita Hill's comments weren't a speech. They were a pack of lies delivered in an unconvincing monotone by an utterly dishonest individual. Even if you believed her crap, I can't see how something so unemotionally delivered could leave much of an impression.
agreed it's a great speech and underrated, but disagree (quibble) as to the reason for its greatness. From 1964, to provide a roadmap to the end of the Soviet Union, as it did,25 years later, makes it one of the greatest speeches of history.
