First and Ten.

It's unofficial - Wesley Clark will become the tenth contender in the crowded Democratic field and - barring an early screw-up of monumental proportions - has to be considered one of the frontrunners immediately. It'll be interesting to see how he shakes up the race - I expect he'll take some of Dean's mavericks, Kerry's military men, and, perhaps most importantly, Edwards' Southerners. (Perhaps sensing the threat, Gore alumnus Chris Lehane left the Kerry team.) In other election news, Edwards officially announces his candidacy (Poor luck that Clark'll steal his media today), while the NY Times's David Brooks examines why GOP ops love Dean. (I, for one, don't really buy it - Dean has to be more worrisome than a milquetoast like Graham.)
