Dean is in Georgia to give himself an excuse for not winning Iowa, I think.
Good point. After being the clear front-runner for a while now, expectations are very high for Dean.
It's kind of like the stock market's reaction when a company releases earnings. If the market is expecting a 50% increase in earnings, and it's only 48%, the stock will drop. But if the market was expecting a 30% increase in earnings, that same 48% increase will make the stock go up.
Same thing with Dean. He needs to lower expectations of a clear Iowa win, and make a very tight victory, or even a second place finish, seem respectable. Otherwise, an upset by Kerry or Edwards will seem to be a big victory, while anything short of clear victory is a defeat for Dean. Ah, the perils of being a front runner.
