Winning Iowa may well boost Kerry back into the lead in NH. NH is his back yard, and he was supposed to do well there. If the NH Dems sense he's now got momentum, they may dump Dean and join Kerry. If he wins Iowa and NH, he'll become the Dem favorite to win it all.
But watch the remaining candidates start ragging on Kerry once he has the lead.
Iowa is rejecting the far left wing as pushed by Dean and his youngsters.......
