In August 2006, the Democratic National Committee adopted a proposal by its Rules and Bylaws Committee stating that only the four states of Iowa, New Hampshire, Nevada, and South Carolina would be permitted to hold primaries or caucuses before February 5, 2008. In May 2007, the Florida Legislature passed a bill that moved the date of the state's primary to January 29, 2008, setting up a confrontation with the DNC. In response, the DNC ruled that Florida's 185 pledged delegates and 26 superdelegates would not be seated at the Democratic National Convention, or, if seated, would not be able to vote. In October 2007, Democrats from Florida's congressional delegation filed a federal lawsuit against the DNC to force a recognition of its delegates, but the suit was unsuccessful. The presidential candidates promised not to campaign in Florida.
