Chappaquidick killed Kennedy's Presidential aspirations.
Why not have Bumpers instead at the head of the ticket. Dale could've beaten Dole.
One problematic thing: Bumpers was up for re-election for Senate in 1980. Doubtful, he'd run for V.P.
Chappaquidick was a major problem, yet with nomination and after hard four years under Republican administration (as Ford term goes basically the same as Carter's) it's hard to imagine Republican winning, even if this would be narrower.
Also, one funny thing. While I understand politics, I never understoof Winfield hate toward Kennedy.
