"Hamilton left the constitutional convention in disgust because they wouldn't abolish the state governments.", Where in the heck to you get that tid-bit of misinformation?
Oh I don't know. How about history?
Hamilton's plan, the so-called "British Plan", explicitly called for the abolition of state sovereignty. Its highlights were:
- A bicameral legislature
- The lower house, the Assembly, was elected by the people for three year terms
- The upper house, the Senate, elected by electors chosen by the people, and with a life-term of service
- An executive called the Governor, elected by electors and with a life-term of service
- The Governor had an absolute veto over bills
- A judiciary, with life-terms of service
- State governors appointed by the national legislature
- National veto power over any state legislation
