Separation of powers. You can't have executive agencies setting laws unilaterally. Congressmen represent We the people and our states. They should have the ability to deny federal agencies their unrestrained power. Individual state legislatures should also be able to override the overreach of executive agencies, like the federal land grab in Utah recently, or the EPA messing up the river out west last year. Federal agencies should not be able to ride roughshod over individual states, and Congress should have the power to limit the overreach of executive agencies. Congress already has those powers through the US Constitution. It is scary how many people are saying No. Do they not understand the separation of powers enacted in the Constitution and how much power we the people have through our elected representatives and how much power we are giving up by allowing unelected bureaucrats to determine how we live?
