You haven't been keeping up with current events.The top down system of control went by the wayside with the anti commandeering doctrine.They could no longer require state's to enforce a federal regulatory scheme.Whether it would be nuclear waste,Hand guns laws or immigration laws.There are now EPA arguments that could lead to Congress trying to restore the top down system of control.I will bet they will stick with conditioning federal funds.The problem is if they usurp the state powers then they have to pay for it all and they will never do that..that is why these high court rulings are never implemented.They just load up the federal grants on conditions to adopt a federal policy then slowly withdraw the funds,and then the state restores the funding to keep getting the smaller percentage of funding.The trick is to get the state ramped up with jobs then have the state step in the keep the jobs.This has been going on since Krakatoa exploded.
Like I said step away from the ACLU and Norml circulars..they lie like rugs they need the public to believe just as much as law enforcement does.And the 10,000 people that hold federally funded state jobs.
