#1: Become a true democracy. Shut down the electoral college, absolutely no use for it in this day and age.
#2: Go back to the original constitution and bill of rights. Everything we needed was right there. That would mean shutting down all federal programs that are not authorized by the constitution. That would mean the only federal programs left would be National Defense and Foreign Policy. No FBI,DEA,FCC,SSI. Nothing. The states could take it over if they wanted too but don't have too.
#3: No attorneys are allowed to run for public office.lol I don't think that one would pass the constitutional test but its fun to dream.
#4; No natural plants or substances can be banned. It takes a pretty sick society to ban nature.lol
