Anyway, came across this WSJ article on how those lines may influence people watching CNN. Here's a quote:
"We don't realize how much we are influenced by other people," said Steven Fein, a social psychology professor at Williams College who has used footage from residential debates in experiments examining how voters might be swayed. "We can't ignore what we think other people think."
Damn right. Remember my infamous quote from that old old play: Public opinion is no more than this, what people think other people think. Nice to see someone else go that direction. And this makes twice in one day I've drawn from the Wall Street Journal. A new record for me.
