deep resentment toward civil rights and really toward African-Americans was a poison in American politics for at least 30 years, from the 1950s all the way through the '80s. And really, not even over the hangover today.
The biggest POD I can see is how Eisenhower reacts toward Brown v. Board of Education.
However he wants to rage privately: the fuck they could have given me a heads-up, I'm only the President of the United States! (don't know if this was the specific issue, but there were aspects of how the decision came down which really rubbed him the wrong way)
in public, Eisenhower supports the decision with matter-of-fact confidence.
In fact, he plays the card, Negroes served honorably and with distinction during the war and are entitled to full rights of citizenship. Not half rights. In America, we do not have second-class citizens, or at least we should not. In America, all citizens are first-class citizens.
* and notice how the language works against us. For example, African-American is just a much better term.
