TallPine,
The US tried that already. The Articles of Confederation, it didn't work. For example, would you need a passport to from state to state? Tarrifs between states, money. As much as I hate it, there are valid reasons for a federal form of government.
Go back and read what Jefferson and Madison had to say about it. The problem, IMHO is that today we have more people who owe their income to the Federal Government. Before the income tax was written into the Constitution, the largest department in the federal government was the Postal Department.
Today, our politicians buy votes. They just don't walk up to people and say if you vote for me I'll give you 1000 dollars. Instead, they pass pork projects. Look at Byrd in West VA. He's an expert.
This is what's got to change, we need to refocus on the core job of the Federal Government. Domestic trqanquility, Common Defense the Common Welfare. Not all these vote buying schemes of politicans. Where are the leaders like Adams, Jefferson, MAdison, Payne, Franklin, Hancock, and Lee.
