Nowhere in the state did the process veer more off course than in St. Charles, a key prize for the Romney, Paul and Santorum campaigns.

Because St. Louis County’s caucuses were divided into 28 township meetings, St. Charles County was slated to assign more delegates than any other single location on Saturday. Jackson County, which includes Kansas City, has more delegates, but, like St. Louis city, asked to hold its caucuses on March 24, so as to avoid a conflict with St. Patrick’s Day.

The caucus in St. Charles County, which was held at Francis Howell North High in St. Peters, was adjourned after police said they were going to “shut us down,” according to Matt Ehlen, the Republican activist who was named chairman of the meeting. Police said 2,500 people showed up, although organizers put the number at less than 1,000.

“For the safety and well being of the attendants at the caucus, we had to adjourn the meeting,” Ehlen said.

However, several individuals at the caucus said much of the consternation revolved around Ehlen himself. Ehlen became chairman after a voice vote, but the head of the county GOP organization failed to recognize any other candidate.
