Joe McCarthy became POTUS, red scare getting worse as we thought indeed. But meanwhile, he strongly supported civil rights movement , he declared Jim Crow law is a shame on all the American people, Red monsters are mocking American, it need to be destroyed, that's only way to defeat Soviet. He invited young priest Martin Luther King to the White house, discussing the potential civil rights act.
( People always think he become POTUS would mess up everything, would become dystopia… but OTL he actually stand with the African American. )
