According to the Los Angeles Times, democrats are considering a scheduling change in regards to the convention. The talk is that while the convention runs Monday - Thursday, closing the convention on Wednesday would give Obama a boost in the polls and extra day to bask in the spotlight. It is further believed that McCain will announce his running mate on Friday before the start of the republican convention the following Monday, a tactic to keep Obama's spotlight limited.
In the article nothing is mentioned about the possible idea being related to funding issues which has plagued the party. One has to wonder if this could be the underlying reason for such a move. The article does mention that it could be too late to make any schedule changes and that Denver officials and the business community would probably not be happy with the idea.
