From Yepsen in Iowa:

GOP activists around the state say that while former Massachusetts Gov. Mitt Romney has a traditional campaign organization, there is little evidence of a statewide Huckabee organization, although the former Arkansas governor also is being helped by networks outside his campaign. “His organization is fairly invisible to me,” said Ann Trimble Ray, the Republican chairwoman from Sac County — located in the most conservative section of the state. “They are recruiting from a different pool than we usually find our activists coming from.”
