Rules, pt. 1
From The Green Papers
On 1 December 2007, the DNC determined that the date of Michigan's 15 January 2008 primary violated party rules and has decided to strip the state of its delegation. The determination was made official on 5 January 2008. Michigan had 128 pledged delegate votes (83 district, 28 at-large, and 17 PLEO) and 28 unpledged delegate votes (17 unpledged DNC members, 1 Governor, 2 Democratic U.S. Senators, 6 Democratic U.S. House Members, and 2 add-ons). Total delegate votes changed from 156 to 0.
Senator Clinton placed her name on the ballot.
Senator Obama did not, along with Senators Joe Biden, John Edwards, Governor Bill Richardson
Senator Clinton was selected by 327,419 of the voting Dems, 55.28% of those who cast a ballot.
As Joe Biden, John Edwards, Barack Obama and Bill Richardson followed the DNC's rules and did not allow their names to be placed on the ballot, and as the MDP discards write-ins, those candidates gave guidenace to their supporters to vote "uncommitted".
The "uncommitted" vote was 236,955 of the voting Dems, 40.01% of those who cast a ballot.
The "soft pledged" delegate count:
Senator Clinton: 79 (50.64%)
Uncommitted: 55 (35.26%)
