I don't believe any of those guys has enough experience to run the country. Clinton took 3-4 years to catch on. Bush still hasn't caught on. I want to see a whole bunch more of Clark before I believe in him. And a whole lot more of Dean, although I like him. It's a job that requires a lot more in the way of understanding, political skills, communication skills and force of personality than specialized knowledge.
I disagree with Mick. This election won't be won in the "great middle." Things have changed a lot since 1992. Even a General from Arkansas is not going to carry Arkansas, if he's a Democrat. To win, a Democrat is going to have to bring out the Democrats, en masse, in places like Ohio, Florida, New Jersey. To do that, Clark will have to discover some populist roots. Bottom line: I vote for whoever the Democrats nominate (unless it's Lieberman - then I guess I turn Green).
