I had a chance to hear Dr. Dean speak in October 03. He is a fine speaker, but Dr. Dean was never a trial lawyer.
Like actors, trial lawyers learn to project their voices to the back of the room. I know because I come from a long line of them. (The tendency skipped me. But my sister has tried cases.) Doctors don't need to make themselves heard as a rule. Dean doesn't project, he shouts.
At his famous "Scream" speech, he was competing with a room full of screaming enthusiasts. The media blocked out the background noise, and made him look like a lunatic.
The campaign could have used that, and I wish they had.
It was moved, seconded and passed that John Kerry was electable, and the other candidates weren't. So, the Democrats went with Kerry, who wasn't quite as electable as they thought.

Mr Gibson, everyone knows you can use your shift key. You don't have to use it again.
