Theresa Colaizzi has withdrawn from the Pittsburgh City Council race against council President Doug Shields.
Her departure means Mr. Shields has no opponent for his council seat. He is also running for city controller against four opponents.
Ms. Colaizzi, of Greenfield, is a member of the city school board. "The more I thought about the school board, and the more I thought about all of the initiatives we're working on, the more I wanted to finish it," she said yesterday.
She has led the successful effort to extend Superintendent Mark Roosevelt's contract.
If Mr. Shields wins the controller's race, he would have to resign his council seat, and a special election to replace him would ensue. If that happens, Ms. Colaizzi said, "then I'm back in the game."
