That is exactly what the Clintons are in the careful process of orchestrating. Wes Clarke is the key. He is the key to convention chaos. But there is a backup plan in place as well.
Here's what I predict:
Clarke/Clinton
It is the perfect win/win situation for Hillary.
If Clarke gets the nomination and wins, it sets up Hillary for '08 against a non-incumbent. (Yeah, Clarke knows why he is there and he would most definitely NOT seek a second term. Or ELSE, LOFL! The Clintons have that in the bag already.) If Clarke loses, it will be Clarke who lost, not Hillary, so she saves face. In either event, she is set up for an '08 run. Win/win (for her).
That's why its imperative for Dean to get the nomination. I hereby withdraw my support of Al Sharpton in all polls that I freep!
