Obama made a 6:15 pm CST stop at Ankeny High School in Ankeny, a suburb outside of Des Moines. The high school was the site of four precincts, and Jen Psaki a spokeswoman for the campaign said it was considered very important for the campaign to win.
The campaign did not tell reporters where Obama had gone until about five minutes ago, claiming that they didn't want to bring the media because they might offend caucus-goers. Yesterday they had scheduled a caucus stop on the schedule for today but pulled it off mid-afternoon.
Obama spent most of his time, according to the campaign, talking with first time caucus-goers.
Deputy campaign manager Dan Pfeiffer told reporters earlier this evening to expect Obama to be behind for the most of the evening, since his strongholds are in more populated counties, especially around Des Moines where the results may take the longest to predict.
Obama has returned to the Residence Inn in West Des Moines to watch the results with his family.
