CEDAR RAPIDS - The key to winning the Iowa Caucus is a well-organized operation that can turn out voters and keep them committed.

The process begins at 7 p.m. local time. Campaigns are asking voters to leave their home in the cold and wet to go to a precinct to write down their candidate's name on a piece of paper. It takes organization and reach to convince enough voters to do this. Caucus goers will hear five minute speeches from representatives of the campaigns, and then they turn in their votes. The whole process lasts an hour.
