He shows every sign of dementia. Has for years. Look at his language, how it's deteriorated even since taking office. The mood swings, the lies, the erratic behaviour..... Remember, he's 71 and his dad had Alzheimer's so there is a genetic link. It also explains why Ivanka has to be in every meeting and Jared has been appointed to everything. He needs people he feels comfortable with close by. I've had a family member suffer from dementia and the rest of us have been watching Trump since the campaign trail saying "well, that's familiar." If he makes it to 2020, I'm guessing by that point, there will be no hiding it and we will hear how he misses the private sector and has decided not to run for re-election. Then he'll fade into obscurity. Hopefully nuclear war hasn't broken out first
