Philadelphia isn't interested in having the Democratic National Convention here in 2012 but is pondering a bid in 2016. Mayor Nutter recently told Democratic National Committee Chairman Tim Kaine that the high costs of holding a convention, including police overtime, precluded a bid for the next big Democratic get-together.

"Our analysis suggests the costs associated with preparing for and hosting the 2012 DNC are important not to overlook," Nutter wrote to Kaine. He also said he wanted to "commit to being first in line to bid on the 2016 Democratic National Convention."Miriam Hill
