It is with sadness that I write to tell you that I am resigning from The New York Times.

I joined the paper with gratitude and optimism three years ago. I was hired with the goal of bringing in voices that would not otherwise appear in your pages: first-time writers, centrists, conservatives and others who would not naturally think of The Times as their home. The reason for this effort was clear: The paper’s failure to anticipate the outcome of the 2016 election meant that it didn’t have a firm grasp of the country it covers. Dean Baquet and others have admitted as much on various occasions. The priority in Opinion was to help redress that critical shortcoming.
