Events have now justified the argument that seating Florida and Michigan in full back in May would have had no material effect on the outcome and could have been done then.
On May 27, I posted a diary arguing that the Florida and Michigan delegations should be seated in full since by that time their effect on the outcome was nil. Their main motivation in moving up their primaries was to gain influence over the nomination process, so that when the delegations were stripped they lost any influence because the nomination was effectively decided in the subsequent primaries.
I got raked over the coals, with most vehemently arguing that there should have been a penalty for breaking the rules that all parties had agreed to. Fair enough--I'm a big boy and I can take it. But I wasn't alone in this argument. On May 23, PocketNines posted a detailed argument, based on the delegate math at the time, for full seating because Obama's advantage was insurmountable under every conceivable scenario. He also predicted that Obama would pre-empt the May 31 Rules and Bylaws committee by agreeing to full seating in advance. That didn't happen, but only the timing was off. Yesterday Obama, in a letter to the Credentials Committee, finally called for full seating.
So let's give full attention to the task of electing Obama!
