The New York Times is doing what journalists are supposed to do when the president of the United States is running for re-election: checking if he's still all there. The paper has actually arrived very late to the party with respect to pointing out Biden's mental issues; but now that it has arrived, it should be applauded and encouraged to continue reporting on this topic. Despite claims that it could help Trump, the Times is carrying out its duty to report on the facts wherever they lead.
