I had not doubt that the Dems would ultimately change the rules for FL and MI. It is their standard operating procedure when the rules don't fit their agenda. It is the same as the Senate race in NJ when Lautengburg broke the rules and entered the race after the very clear agreed upon deadline.
They know by completely banning the delegates of FL and MI, even though that was the rule and EVERYONE, including Dean, Clinton and Obama, agreed to those rules, they risked alienating two very important general election states.
Their solution will only serve to create more rifts in the party which will help McCain, who needs absolutely all the help he can get b/c he is not doing much to shore up his right flank with the conservative base, in fact quite the opposite. This will no doubt be one of the most interesting elections in history as it already has proven.
