My granddaddy voted without knowing what the candidates looked like, or how expensive their wives' sweaters were. TV and internet have changed the way we do politics. We have too much information about our options and it spoils our view.
The Sunday NY Times contains more information in one day than the typical person 100 years ago would be exposed to in their entire lifetime. There is no "ideal" candidate, they're all liars, cheats, and live privileged lives most of us can't comprehend. We didn't used to know that, and we were happier. Ignorance is bliss.
