From the Associated Press comes this news about a press conference today in Florida where the head of the Florida Dems expressed extreme pessimism about a solution to the revote standoff...

TALLAHASSEE, Fla. - The head of Florida's Democratic Party said Thursday the proposed vote-by-mail presidential primary is unlikely to go forward because of strong opposition and concerns about conducting the vote.

Karen Thurman said she is asking Democratic leaders, the national party and presidential candidates Sens. Barack Obama and Hillary Rodham Clinton to consider the option as the best way to resolve the delegate dispute. Florida had all 210 of its delegates to the national convention stripped after it violated national party rules by moving up its primary to January.

When asked if the alternative will be implemented, knowing what she knows about potential problems executing the plan and widespread concerns, Thurman said, "I have a feeling that this is probably closer to not, than yes."...

"If this becomes something that we can't do, then we can't do it," Thurman said.

There are multiple problems. First, there are procedural difficulties in getting such a thing implemented. What's more, the Obama camp has concerns about a mail-in scheme, and today on CNN Howard Dean said the DNC wouldn't back any plan that isn't favored by both campaigns: "We’d like to do it in a way that’s fair, that both sides believe is fair. Fair to the voters but also fair to the campaigns."

So what's the upshot? I checked in with DNC spokesperson Stacie Paxton, who said:

There are two options. They can resubmit a plan and run a party process to select delegates or they can appeal to the Convention Credentials Committee which resolves questions about the seating of delegates.

What this fundamentally means is that there's little that the DNC can do to resolve this -- if Florida officials don't agree on a plan, and one that's acceptable to both campaigns, to boot, it's all but certain that there will be no revote at all.

And what happens then? Well, Florida officials can appeal to the DNC's credentials committee, which will consider various plans to get the delegation sat in some form or other. At that point, it's anyone's guess what will happen. In short, mayhem is on the horizon.
