It happened during the 1996 Republican Convention. Senator Bob Dole stood up and said that the White House was filled with people who had "never accomplished anything." This struck me as an inter-generational slap against the Baby Boomer generation by a member of the Greatest Generation. "We won WWII and all you did was smoke dope!"
Now McCain is trying to paint an Xer as naive while we must trust the worldliness of his Silent Generation. I wonder if this sort of thing signals "past it!"
