Cummings has no worries, he knows he is set for life. His Baltimore constituency is an ignorant mass of urbanites who love his gimme-me-mo-stuff-and-stick-it-to-the-man crap.
It seems you are right, he has no worries. Whatever his own office is or is not doing matters not. Does he even go to his office? Can you imagine, admitting in public you do not know what goes on in your office? I would call that incompetence.
