I expect a little more from my elected officials!
Alright, with a briefer red scare:
1) Both the Kennedy and Johnson administrations have a closer relationship with MLK and the Civil Rights movement in general. In particular, they're not put off by the fact that he sometimes gets advice from Stanley Levison, and then Martin makes up his own mind thank you very much.
2) A higher trajectory for the American union movement, more citizens right now in 2017 in the middle class. And probably, a more left-leaning, humanistic, realistic foreign policy, with much more emphasis on building people up (yes, I can be pretty idealistic, and so can you

)
