Years ago, I attended a campaign rally for George McGovern.  It was a small gathering on a college campus in California.  The only thing I remember about the event was McGovern's finger.  The whole speech he was waving that finger at everyone, like a minister in church threatening eternal fire if his preaching wasn't followed.  That finger, which seemed bigger than a finger should be, put me off more than anything McGovern said.  It struck me as condescending and disrespectful of the audience, a sign of someone who thinks he knows better than the rest of us.
