I have found some interesting facts while watching C-Span last night. The minority leader of the Florida legislature was on.
He said that every state which moved up their primaries were originally told that their votes would not count but after a DNC meeting in Atlanta, these same states were granted an exemption except for Michigan and Florida.
The Democratic minority in Florida Legislature tried to get a bill passed moving the primary back to February 5th put the bill was voted down by the majority Republicans in the legislature.
All candidates signed an agreement that they would not campaign in Florida but all candidates names were left on the ballot
