Well here's why/
At his swearing in he was supposed to swear to UPHOLD THE CONSTITUTION
What he clearly must have heard was HOLDUP not UPHOLD.
So he thinks he is doing a he** of a job holding it up. No wonder he is so confused by folks who say he isn't doing a good job. He thinks he is.
When you think backwards see backwards do backward organically not knowing any better of c ourse you think you are being crucified for doing such a swell job.
Who is held up the tenets the Constitution any better? Who is ignored the Emoluments clause? Who has ignored completely that CONGRESS is an equal to him and the HOUSE holds the pursestrings not him? He is holding up everything all the time as best he can and is completely unaware of all his criminal activities. He believes he is supposed to be doing what he is doing.
