The Florida Democratic party had caucuses last weekend; as far as I know these don't count any more than anything else Florida Democrats do.
The numerical results were determined by the voting in the Florida primary. The issue at the caucus was who would get to be the actual delegates.
How are the district-level caucuses run? Who chooses the delegates? The selection of district-level delegates will be in 25 post-primary district-level caucuses around the state on March 1, 2008. The highest vote-getters slotted under each presidential candidate are elected. (The numbers each presidential candidate gets in each district is dependent on the Presidential Primary results in that district.) In order to participate as a voter in the caucus, a voter must establish that he or she is a registered Democrat within the Caucus' Congressional District. Voters must present a voter registration card and photo I.D. The voter will then be required to fill out a statement of support for the presidential candidate whom he or she supports. Delegates and alternates will be elected only by those participants at the caucus who have declared support for the same candidate to whom the delegate or alternates are pledged. Each participating voter must vote for exactly the number of delegate candidates to which the presidential candidate is entitled. Undervotes and overvotes will result in that ballot becoming invalid and will not count.
