Back when the USA was being formed, it was really just a bunch of INDIVIDUAL states that wanted strength and protection from outsiders (other countries). The original idea was to let each state "do its own thing" with little intervention from a single Federal government. When did things go so wrong?
Currently there are dozens (hundreds?) of Federal Laws that are essentially similar to, or even often contradict, state laws. This is a total waste of taxpayer money and government effort. One quick example I'll give pertains to marijuana - voted legal for medicinal use in California yet still against Federal Law.
The Federal laws which contradict state & local laws must be abolished. The Federal Government needs to do the things it does best, or the states can not do (protect our country/borders, provide social security, provide health care, etc) and stop interfering with the states.
