Eh... Context is important. I think if he had overcome his disability and managed to power through it to achieve a decent education that would actually be a plus.
Instead he has a bachelor's from an expensive private school where he "studied" abroad. I think it's just indicative of his history of being able to rely on connections and money to achieve his position in life. And it makes me doubt that he is educated enough or willing to work hard enough to learn all the things someone should know to be president of the United States.
As someone who has a neurodevelopmental disorder, my problem isn't that he has a learning disability. It's that he's a rich fuck boy with a learning disability, which is a powerful combo. I know if I had a friend who just gifted me multi-million dollar businesses that allowed me to do whatever I wanted.....I would be an idiotic terror.
