Iowa (BEESIA) Republicans will get the first crack at selecting a presidential nominee tomorrow by casting votes in a caucus process that’s become best known for ending or fueling candidacies rather than predicting the nominee.

Based on past patterns, a fraction of Iowa (NFSEIA) Republicans will attend the 1,774 caucus meetings held at 809 locations — schools, community centers, churches and other public venues — at 7 p.m. central time.

Each presidential campaign may have one surrogate speak for as long as five minutes. Attendees cast their votes usually by writing the candidate’s name on a piece of paper that they deposit in envelopes or boxes. The vote-counting is public and may be observed by representatives of the presidential campaigns.
