What got Kennedy elected was his good looks as compared to Nixon's five o'clock shadow. (Plus a little vote fixing by Daley and the Mob.)

Eisenhower, on the other hand, was neither responsible for the prosperity and peace of that historical period, nor was he to blame for it being bland and sort of tacky, culturally speaking. He just happened to be there at the time, that's all. ;-) He was, I think, basically a good man.
