Not really, what you have to remember is why the U.S. supported Franco: It wasn't communism. Obviously now we look back and ponder why the "Ultimate representative of democracy" would ally with a dictatorship. But due to the help Russia was giving to the Republicans, America felt it was necessary to help the Rebels.

Even once the war was won by Franco and he declared himself dictator, it wasn't a dictatorship like, say, North Korea. People were free to emigrate, they couldn't speech freely, no; but Franco helped the country develop (Social Security. etc).

President Dwight D. Eisenhower even visited Spain and Nixon is quoted to have said that Franco was "a loyal friend and ally [...]". Everyone was more fearful of Russia and the communist expansion.

Obviously there wasn't a complete unanimous agreement that the U.S. should back Franco. Thousands of Spanish-American women protested in Washington DC in 1938, but after Spain tried and failed to become a self-sufficient society, help was wanted and needed, regardless of who that was, everyone rather it were America, not the USSR.
