important is that on a night like tonight? >> reporter: well political insiders tell us it is going to be very, very telling tonight. the people who have spent months or more here organizing all of their precinct captains, surrogates, supporters. tonight it's a cold, lengthy process for somebody, it takes patience and commitments. you want to make sure all the doors you knocked on, all the people you got to commit to you will turn around and get everybody out to vote. we talked with the governor's office and they say listen it's like nothing else and tonight the organization will show. take a listen. >> the campaigns with the best organization are going to call up every single last one of their supporters, which could number in the 20 to 30,000 range and make sure they know where to go on caucus night. organization also matters because at these individual precincts, and there is 1,774 throughout the entire state, you want to make sure that you're campaign has a precinct leader. >> reporter: all right.
