I greatly admire the form of government the founders of your nation devised. Unfortunately several legislative and judicial decisions in the 20th century have eroded the republican form of government to the extent that the country seems ungovernable.
A return to actual form of government outlined in the constitution would rectify today's problems.
That is essentially impossible given the deliberate subversion of our political processes and institutions. Our form of government requires a moral people and Americans are very far lost into decadence.
Read "The Shadow Party" by David Horowitz and Richard Poe to learn how corrupted our institutions have become. The book was published in 2006 and matters have become far worse with the election of Obama and his radical henchmen. America is locked in the throes of a quiet but deadly revolution.
