I knew I shouldn't have let myself think that somehow Barack Obama was going to lock up the Democratic nomination by next Tuesday's final contests on June 3.

I should have known better than to think this would just end cleanly.

That's because when the Democratic National Committee's Rules and Bylaws panel meets on Saturday to discuss the Florida and Michigan delegate situation, they could actually find a resolution that sends Obama in reverse.

How, you ask?

Well, let's say the committee decides to cut the two delegations in half and apportion them according to how the two states voted, or some agreed upon split between Obama and Hillary Clinton.

Well, if that happens, then the Obama Magic Number would go up, because there would be a different number of delegates needed for a majority.

"Our magic number could increase kind of at the 11th hour," acknowledged Obama campaign manager David Plouffe.

"But at some point we're the nominee."

There are many different mathematical ways that the DNC could divvy up the delegates from Michigan and Florida, so it's hard to know how much the Obama magic number might grow.

But as Plouffe says, there really is no situation in which Clinton can get so many delegates that suddenly she's on the verge of being the nominee.

So when you hear all the yelling and screaming this Saturday about Florida and Michigan, take another sip of your beverage of choice and realize that while there's a lot of heat, it's not going to change the direction of the race.

As for the candidates today, Hillary Clinton is in South Dakota, while Barack Obama takes the day off the campaign trail. 

Puerto Rico votes Sunday, followed by Montana and South Dakota on Tuesday.

Too bad Michigan and Florida didn't get their act together and have a re-vote on June 10.  Then we really would have had some fun.
