Because he is really old
And now 47 is the oldest man ever elected
You'd have thought people would have learned their lesson when last time they elected an old man who clearly, from day one, was no longer mentally up for the job. But instead we put ourselves in the same position again, all because of which too old person is on our team, with an assist from the party that threw out their old, mentally incompetent candidate in favor of perhaps the worst major party candidate for President ever.
