Although I agree that there are negative ramifications in Congress in abdicating its responsibilities in favor of the other two branches, I believe that the erosion of the power of the sovereign states is even more important. Yielding to a central, federal authority in increasing areas is not good.
The combined power of the states holds the ultimate authority in this country. Wielding that power, they can accomplish anything, including the dissolution of Congress, the removal of the President, and the firing of the Supreme Courts.
