What did Nixon have? I've read a lot about him being very shy. Not sure if it was anything more then that.
Nixon probably suffered from some combination of depression and paranoia, but there's no way he was on the autism spectrum. He was way too skilled at reading people and manipulating them to have been autistic. Also, he may well have been a sociopath.
And also, it's very unlikely we've had, or ever will have, a president with Asperger's. Just like 95% of people on the Internet who think they have Asperger's don't and are just nerds, most of the people who have been mentioned on this thread as potential candidates for Asperger's or the autism spectrum were just depressed, introverted, or socially maladroit.
