I agree w/ the choices he has made, agencies he has chosen to go after:
EPA, HUD, Education, and Energy.
I know of landlords who seriously abuse the HUD program, couldn't care less about the tenants (allow bug problems to worsen, ignore other livability issues, etc), who only try to get rich off the governemnt (and the disadvantaged and elderly) by charging far more for an apt than it is worth, and possibly more than they could get on the open market
EPA... we all know how they made even small puddles on farms a “US waterway,” and as a result farmers and ranchers can't use some of their land to grow food for us..
Education... Ahh... Do I even have to explain that one? I don't think so
Energy: ditto
