Biden

Fox News' Peter Doocy: "How bad is your memory and can you continue as president?" Biden: "My memory is so bad I let you speak." 

Paul Krugman, NY Times - I had an hourlong off-the-record meeting with Biden in August. I can’t talk about the content, but I can assure you that he’s perfectly lucid, with a good grasp of events. And outside that personal experience, on several occasions when I thought he was making a serious misjudgment — like his handling of the debt ceiling crisis — he was right and I was wrong.

And my God, consider his opponent. When I listen to Donald Trump’s speeches, I find myself thinking about my father, who died in 2013 (something else I had to look up). During his last year my father suffered from sundowning: He was lucid during the day, but would sometimes become incoherent and aggressive after dark. If we’re going to be doing amateur psychological diagnoses of elderly politicians, shouldn’t we be talking about a candidate who has confused Nikki Haley with Nancy Pelosi and whose ranting and raving sometimes reminds me of my father on a bad evening? So to everyone who’s piling on Biden right now, stop and look in the mirror. And ask yourself what you are doing.
