@GottaLaff In the past I've heard that Trump dictates his tweets because he can't use a phone with his tiny hands. So probably can't blame him for accidental misspellings.
OTOH, I'm not convinced any of this is accidental - Trump gets a lot more attention from the left for acting the fool while it doesn't hurt him at all on the right, so instead of "Trump is losing it" I'm inclined to think "Trump is getting the attention he wants."
