It could have been incompetence, yes… Or it could have been someone who knew this would slip by the Trump loyalists and end up getting published.
True enough. I waffle between good intention and incompetence.

Both things could be true at once.

But it’s far more likely they’re all just that stupid.

Well even if it were intentional, that individual was dependent on the incompetence and they were right.
Oh I get it because they’re stupid
I would do that if given the opportunity.
Ah yes, the famously super-competent FBI directed by political loyalists who’s only qualifications are heavy plastic surgery and blind faith in an evil idiot.
