He's both, sometimes its evident, sometimes its not that clear. On the ignorant portion, and I hope she doesn't get mad at me, but my wife's grandma (rest in peace) would just take tidbits of information and form them into new 'policies'. So Papa had heart issues and was on a drug which he was told not to eat too many green peas. Apparently too much of a certain vitamin in them that could make the drug more ineffective. Did Grandma understand this....no. Instead she preceded to tell the family that they need to stop eating peas because it's bad for the heart. She didn't lie, cheat, and steal, so it was obvious when she said something like this you could trace it back to some info she got. Unfortunately with Trump, who knows, could be lying about it, could be saying it based on some tidbit he's unable to fully process in his brain, could simply be saying it because at the time it sounded like the best way to retort as he really doesn't care if its true or not.
