If the options for a visionary new broom seemed more convincing, I would be happy to be convinced. Otis Rolley’s ambitious, energetic campaign and detailed plans for nearly every issue are appealing in many ways, but some of the details give me pause. It would be great if Rolley could, as he proposes, build 50 new schools in 10 years; it would be great if he could build even five. But he has not explained how this could happen, especially with the 50 percent property-tax cut he proposes. Jody Landers, a veteran public servant and businessman, has stumped for many of the same issues as Rolley (e.g., making possession of small amounts of marijuana a commensurately minor crime), though he can lack the sort of detail that makes such proposals convincing. State Sen. Catherine Pugh, too, is full of fresh ideas, though she lacks executive experience.
