The New York Times and CNN will co-host the next Democratic debate, on Oct. 15, at Otterbein University in Westerville, Ohio — the first presidential campaign debate that The Times has planned and hosted in more than a decade.

The Times’s National editor, Marc Lacey, will moderate the debate alongside the CNN anchors Anderson Cooper and Erin Burnett. He has been busy preparing for the debate and would like to hear from Times readers.
