It will be the first real test of Republican presidential candidates as they seek to earn their party's nomination for the chance to oust President Obama.
Several GOP candidates are hitting Iowa hard this week following their final debate before the caucuses last Thursday in Sioux City.
Former Massachusetts Governor Mitt Romney, who this weekend earned the endorsement of the "Des Moines Register," has no campaign events today.
Minnesota Congresswoman Michele Bachmann is in the midst of a ten-day bus tour in which she plans to visit and speak in all 99 counties in Iowa.
She will start this morning in Hampton and wrap up tonight with a town hall meeting at a pizza restaurant in Waverly.
Former U.S. House Speaker Newt Gingrich has a pair of events in Iowa on his schedule today, starting with a speech at Global Security Services in Davenport in the afternoon.
The current frontrunner in the Iowa polls will also hold a book signing and a town hall meeting tonight in Hiawatha.
Bachmann isn't the only candidate on a bus tour of Iowa.
Texas Governor Rick Perry is doing the same thing.
He has four events on the docket today in Elkader, Manchester, Dyersville and Dubuque.
Former Pennsylvania Senator Rick Santorum, who has spent the most time of any presidential candidate in Iowa to date, starts off this morning with a meet and greet at Windrow Restaurant in Creston before holding a lunchtime town hall at a pizza joint in Osceola.
Santorum wraps up his Monday with a speech at Indianola Christian Union Church.
While those four candidates are shaking hands and kissing babies in Iowa, others are in New Hampshire, where voters will head to the polls for that state's Republican primary on January 10th.
Former Utah Governor Jon Huntsman has a town hall meeting in Londonderry this morning, followed by another in Salem in the afternoon.
