DES MOINES---President Obama talks to Iowa Democrats who will also caucus on Tuesday evening--though most of the attention is on the GOP contest. Obama's comments will come via teleconference as his re-election team has been organizing in Iowa for months.

Obama's team has eight Iowa campaign offices; made some 350,000 calls to supporters with 1,200 grass roots events.

From an Obama 2012 staffer: "Our focus in Iowa four years ago was on turn-out, but with a non-competitive primary contest, we are using the caucuses as an opportunity to expand the unrivaled organization we have built this year."
