Needs to go beyond who's the head of an agency, though that's a good start. The EPA makes regs without any science whatsoever. What 'science' they do try to prop us as the excuse is one sided and only feeds the predetermined conclusion.
Worse is the incestuous collusion with the enviro groups. They sue the EPA to get a judge to sign off on new regs, then sit down with the EPA to write those regs. Unethical and in my book illegal conflict of interest, and that's just one of many issue of how these departments put out regs that we have to pay for and deal with.
Laws need to be passed completely reforming the rule making system by clamping down on agencies, and require strict procedures before their regs can past muster.
