And Richard Nixon was no conservative.
FDR did promote a socialist agenda in the 1930`s and JFK was a 1960`s liberal on many social issues. Malcom X was a militant Muslim, while Barabra Jordon was a black liberal.
The closest any of those top ten come to being a communist is, Martin Luther King. King was made some supportive remarks about communism during his public career.
Get real.
As far as your claim that the OTHER EIGHT speeches on the list (besides Reagan's and Nixon's)were not by communists, here's a little history lesson for you: Communists = socialists = nazis = democrats. Only Communists deny it.
