He was the editor of The News-Chronicle's commentary pages until 1996. A major topic of interest for him has always been environmental issues, for which he has won awards. In 1997, The News-Chronicle published The Packer Chronicles, a collection of Lahey's cartoons about Green Bay's hometown football team (the players, the coaches, and the fans). In 2005, The News-Chronicle was closed by its new owner, Gannett, which bought the paper 11 months earlier. In early 2006, Lahey started creating new political cartoons on his web site. He does three new cartoons a week. His last cartoon was dated Feb. 3, 2013, five days before his death.
