The Obama and Clinton camps have a hard time negotiating a convention deal:
"Former president Bill Clinton is almost certain to play a role, perhaps on Wednesday, Aug. 27, advisers said, despite his lukewarm embrace so far of the Democratic candidate. His apparent reluctance to declare that Obama is qualified for the presidency in an interview with ABC this week left Obama aides rolling their eyes....some Clinton supporters and delegates are mobilizing to attempt to force a symbolic vote, or at least draw as much attention to the Clinton team as possible during the Denver events. Michele Thomas, 40, a photographer in Los Angeles, said she is helping organize delegates who think that only through a roll call can Clinton be properly honored. "If the party is speaking about unity, they [the Clinton delegates] believe the only way to unify the party is actually allowing them to vote," Thomas said in a phone interview yesterday. "Moving beyond the convention, if they were not allowed to vote there would be a lot of resentment."
If you have to keep saying how unified you are as a party, chances are you're not.
