"When I was hired in 1993, The Post-Gazette was the liberal newspaper in town, but it always prided itself on being a forum for a lot of divergent ideas. The change in the paper did not happen overnight. From what I remember, it started in 2011, with the endorsement of the Republican candidate for Pennsylvania governor, which shocked a majority of our readership. The next big moment happened in late 2015, when my longtime boss, the editorial page editor, took a buyout after the publisher indicated that the paper might endorse Mr. Trump. Then, early this year, we published openly racist editorials."
