The name of our nation is “The United States of America,” and yet we repeatedly hear federal legislators say that, "My responsibility is to act in the best interest of the people of my state." They are wrong when they say that, and that is a very big part of the problem this nation faces.
Their real responsibility of a federal legislator elected by the people of a state is to represent the principles which are held by a majority of the people of that state in serving the best interest of the nation as a whole.
When legislators focus is on representing only the best interest of the people of the state they serve then we become the "Divided States of America."
We have, in fact become 485 constituencies (435 districts in the House and 50 states), all fighting for the biggest piece of the pie and willing to sabotage not only each of the other 484 constituencies, but willing to sabotage the nation as a whole in order to fatten the purse of one small piece.
The legislators are not supposed to be "bringing home the bacon" to enrich their constituency, they are supposed to be governing the nation by casting votes in the legislature which are in accordance with principles that are held by their constituencies and which best serve the well being of the nation as a whole.
