I tend to believe that it was Nixon who was hurt by the Wallace vote. After all, the Alabama governor took several states that had gone to Goldwater in 1964.
Nixon probably didn't have too many of those descendants of the Dixiecrats. I read one piece that said Wallace hurt Nixon in the South, and he hurt Humphrey in the North, especially the votes of labor in the cities. My point was more that third parties and our system of an electoral college can have unpredictable results in close elections, since there is so much dissatisfaction with the current GOP.
