Man, sorry to tell you that LBJ won in a massive landslide that covered all categories, it wasn’t the black voters moving from 75% to 94% democrat, and it wasn’t better black turnout, and it wasn’t anti-semitic Jews voting 90% for LBJ.
Goldwater lost everyone, including 60% of men and 59% of the white vote.
But the aggregate numbers tell a totally different story. LBJ won because he got votes JFK couldn’t get.
