The Democrats are famous for constantly telling us how stupid Republican leaders are, while touting the brilliance of their own leaders. (This worked quite well on Dan Quayle, who was executed by the media for reading a misspelled card on the spelling of "potato.")
Where it starts getting fun is when you ask for any real objective facts to back this thesis up.
To a perceptual mentality, how pretty someone talks is probably more important than what they say. I expect I wouldn't make much of an impression talking off the cuff either, as opposed to being able to write my thoughts.
