What influence did Che Guevara have on the mid 20th century United States of America? Che was part of Cuba's revolution where Fidel Castro took over. Even Democrats were opposed to Castro back then.
Democrat Harry Truman got us involved in fighting the communists in Korea. Democrat John F. Kennedy came close to going to war with Castro. Democrat Lyndon Johnson got us involved in fighting communist China in Vietnam.
Make no mistake, I am not defending the Democrat party in any way. The Democrat party has always and still is the party of racism. I am just saying that the communists, fascists, Nazi and other assorted socialists that took over the Democrat party in the early 20th century did not rear their ugly heads until the 60's.
And when they did many Democrats, like Reagan, saw what was happening to their party they left. Not because of racism like the Dems want to say today but because of socialism.
