The Des Moines Register is the biggest paper in Iowa. Here are some of the campaign stories they have filed so far today.

Obama Keeps Pressure On Clinton, Edwards:

Burlington, Ia.- Democrat Barack Obama today kept the heat on his two chief rivals the Iowa Caucuses, taking shots at both Hillary Clinton and John Edwards while describing himself as the best able to change the nation's course. . . . Obama spent more than 10 minutes of a 45-minute speech referring to what he argued were differences between his, Clinton's and Edwards' credibility to challenge the status quo in economic and foreign policy.

Edwards Hunts Second Choice Votes:

Iowa Democrats who support back-of-the-pack candidates should expect to be approached Thursday night by John Edwards fans carrying 80-page booklets spelling out his stances on issues. At every campaign stop, the Edwards campaign has been passing out scores of copies of the red-white-and-blue booklet. Before the candidate takes the microphone, the person introducing him asks supporters to study the pamphlet and carry it with them to their caucuses, where they can use it to persuade supporters of less-popular Democrats to switch to his side.

And from David Yepsen's blog, Hillary Weather:

The forecast for caucus day on Thursday in Iowa is clear with a high of 34 degrees. The day before is also expected to be sunny. That’s Hillary Clinton Weather. The roads and sidewalks will be clean and the ice melted enough to allow older women to get out and caucus for the New York senator. Clinton’s been placing a big emphasis on getting older women to caucus for her. Her events are well attended by them and there seems to be some excitement among some of them about how they can help elect the first woman to the presidency. Women will make up over 55 percent of the caucus attendees on Thursday.
