If its so simple, give me a couple examples.
Article 1 section 8 clause 8, authorizes congress only to promote the sciences and useful arts by providing patients and copyrights. (paraphrased) They are funding useless bullshit.
Article 1 section 8 clause 17, authorizes congress legislative authority over federally owned land. (paraphrased) Meaning the bureaucrats in the EPA and other alphabet agencies have no authority over state of privately owned lands.
I could come up with more but why bother.
For the first one, where have they gone too far? You may think its worthless bullshit like where are all the bees going and are cars causing global warming but trust me, people who are a lot smarter than you go up and pitch their reasons and congress gives them the grant money based on the facts. You may not like it, agree or get it, but then again you aren't on the condo board of directors. You are just a tenant. So if you don't like how the board is being run, you should run yourself. Or you should vote someone in who agrees with you. I'm sure many republican, libertarian and tea baggers would love your vote.
2. The EPA stops corporations in any state from polluting waters that will eventually seep out into other states. Or your smoke stacks are polluting the next state over. You red necks don't get to do anything you want. Georgia or Tennessee might want to build nuclear power plants but then when they have an accident the rest of us have to pay for it.
Face it, you are a member of the United States of America. States rights only go so far. If you are breaking federal law we'll send in the guard and like we stomped Lee's ass we'll do it again to his great great great grandson today, Goober Lee.
