My guess is Biden's and Dodd's supporters will rally around Obama, and with the momentuam Obama has received from the victory in Iowa, he should be able to attract another half of the uncommitted democratice voters (which is about 8%) in NH. That should give Obama the final push towards the victory in NH.

Clinton will come second by a margin of less than 2%.

Richardson could drop out of the race after NH. Poor guy won't have much money left even though he has everything to be an excellent president!

Romney will win NH. McCain's surge in polls lately is largely due to independent voters, who could vote for either party in NH. Independents will be divided over Obama, McCain, and Ron Paul. So, it remains to be seen which side they go with.
