Out of Missouri, another story that will add to speculation about a Romney-Paul alliance:

The campaigns for Mitt Romney and Ron Paul — who, at many Missouri caucus sites, worked in tandem — have prepared a joint complaint alleging "serious and prejudicial misconduct" at the March 17 gathering in Jefferson County.

Both campaigns have asked that the state party refuse to recognize the delegates elected at the county caucus, who, they say, are loyal to GOP rival Rick Santorum.

"They intentionally tried to alter the outcome of the caucus with dirty tricks," said Romney spokesman Ryan Williams. "It's clearly an egregious example of intentional misconduct from Santorum supporters."

The complaint, mailed to the state party this week, alleges that Santorum supporters forced a delay at the caucus when they realized they did not have the numbers the control the outcome.

That delay, according to the complaint, was caused by the "intentional removal" of registration documents needed to conduct caucus business.

"Indeed," the complaint says, "the supporters of Rick Santorum held the caucus hostage until they got enough people to leave so they could achieve the result they desired."
