He's drawing youths, crossovers and educated/wealthy.

Youth we can ascribe to emotional passion, but the crossovers and educated/wealthy are typically people who are more intellectual about politics.

Those two groups seem to be dreading a Clinton II campaign and presidency reminiscent of I's, one of narrow wins, modest offerings and a tightly deadlocked country. Contrasting with Obama who talks like older time politicians in his sense of possibility of stronger majorities and lifting the people up a little to where the fear and hate message of the right is less convincing to them.

I don't personally judge Obama as a great communicator but he's very good with a very positive tone, and no other candidate is very good except for Rev. Huckabee who doesn't look likely to become our opponent.

Dean was in serious trouble expanding his coalition long before Iowa. Obama has not been in serious trouble for months, and is growing stronger. We're all extraordinarily lucky that Dean did so well and as a result got into position to make the party think 50 states before Obama arose.
