States are free to make laws that will only affect their state. Once it crosses borders is when the Feds need to get involved. I have no problem with keeping control at state level. If the state government suck, than the people can change it themselves. If they choose not to change it then the rest of them have a choice, live with it, keep trying to change it,  or move to another state. What's good for one state isn't necessarily good for another.
