At the state level, we'd need a government that:
a) was strong enough to keep out the feds (should be its number one job)
b) kept the legislature and judiciary strong enough to limit each other and look out for the rights of individuals
c) had a constitutional amendment which was much more powerful in prescribing impeachment of judges and legislators who violate their oaths of office, and a very powerful mandamus amendment so that citizens could hold bureaucrats accountable via the civil courts, impeach and/or recall elected officials and judges by petition to the General Court OR the Governor.
d) an amendment saying EXACTLY what government COULD do, and saying anything else it is specifically prohibited from.
