City and county leaders were slated to vote Friday on the proposed $515 million baseball stadium for the Florida Marlins. But after only four commissioners showed up for the vote, Miami commissioners postponed it until March 12. Commissioners spent the day debating the deal. One commissioner asked for several modifications, including greater profits for the city and county governments, from the sale of stadium naming rights. The commissioners had previously expressed worries about how long it would take to pay back debt incurred in building the stadium.
