Mostly though, the show worked because, as I implied, it worked on the personal human level. Edith Bunker probably would come out as one of the half dozen most beloved characters in the history of television, and politics was ultimately ALWAYS secondary to family. The girls had the task of civilizing the men and keeping the family whole. They called the show "all in the family" not "all in the congress." They made humor mostly out of family politics, not electoral contests.
Anyway, they created a great television landmark, arguably the greatest and funniest show in the history of the medium. Other than The Simpsons, what shows even come close?
