This was an incredible scene: Colleen Guiney’s infantry of newcomers to the political system had just seized every County Council seat, the post of district attorney, and a full slate of judgeships in Delaware County. They left not even a crumb for the GOP, annihilating Republicans with the brutal finality of a nuclear bomb. And this in a county where, for generations, you had to at least pretend you were Republican if you wanted to get anything done.
