Plans for spending the money have been laid out, and the cities' share has been decided. The current commission or any future commission, regardless of how its members are elected, could change the county's spending plans, but it would risk the wrath of voters. More government is unnecessary. There has been no citizen demand to increase the size of Pinellas County government. But there has been a demand to make government more responsive, which district elections would accomplish.
More government is less control.
Today a simple majority of three sets policy for the county. With seven members it will take a majority of four to establish policy. District elections offer more control. Voters would find it easier to elect candidates and oust incumbents. District commissioners would be more responsive to constituents and more aware of their concerns.
