Jan. 3 will be the second Iowa caucus. As pointed out by an astute young operative, the first one took place yesterday as families gathered to worship, eat, open gifts and catch up. If folks were chatting about the presidential race in Oregon, where Playbook spent Christmas, you can be sure they were talking about it from Ackley, Iowa to Zearing, Iowa, and at every Eagle Grove, Mason City and Sergeant Bluff in between.
