That cognitive ability test
Trump took. Remember, he asked to be tested, and we have heard from various sources that there is a standard test given to old people to check for early signs of dementia. What do you want to bet that he was given the test ahead of time--because they knew which test it would be--and prepared for it?
I suspect he would be able to pass the test anyway--as I recall, you're asked to draw the hands on a clock face to indicate a particular time, to draw a cube, and to follow-the-dots in a mix of numbers and letters (A1 to B2 etc)--but I think knowing ahead of time that he would be able to pass it without any trouble was important because older folks like me can be easily rattled when confronted with something unknown.
I mean, every single doctor who has commented on this has known what the test would be. How hard would it be for Trump's staff to ask his doctor--the goofy one--what kind of test he'd be given on cognitive abilities?
