We can't trust the federal government to make sure the federal government doesn't break the rules.  Although I would prefer the people to be in charge, it isn't practical.  We need the states to be able to overrule anything the Federal government does and punish any federal politicians who break their oaths.  Although it isn't explicit, I believe that was the understanding when the constitution was written.  We need to get back to the states being a check on the federal government instead of purely subservient to the federal government.  Going back to states appointing senators would also help. 

 And the counties a check on the states. 

 Absolutely.  Bring the power back closer to the people.
