Once more, I think I understand why so many still support Trump,

especially in Congress.

Over the years, I've known a fair number of people who, for whatever reason, seemed incapable of, or just downright refused to, admit making a mistake. They have included friends, relatives, classmates, co-workers, managers, and many others. They would get defensive and start blaming others, or change the subject, or clam up, or get in a huff and walk away. In some extreme cases it wasn't even that they made a mistake: sometimes shit just happens, but some of these people would immediately start looking for someone to blame, 'cuz it certainly wasn't "their fault."

That's what I think I'm seeing here, and it's so obvious with some of the questions or remarks (and the tone) fired at people during Congressional hearings. It's like they're digging in and refusing to address the issues and using their time to point fingers at someone else.

I don't have a clue why some people behave this way, but it's very noticeable if you just stand back and watch it. In the case of elected officials, of course, it's likely that they're afraid to admit a mistake because it might cost them the next election.
