It really began with Roosevelt...Teddy not Frankenstein.
The Constitution has been under relentless, constant attack by liberals/leftists since 1934.
It began earlier than that, when the right to leave if the Feds violated their Constitutional limits was forcibly crushed.
The ONLY ones who have abandoned the Constitution are the dimoRATS. They have tried to take over the position of Commander-in-Chief, Secretary of State, Director of the CIA, and Chairman of the Joint Chiefs.
Any serious Founding Father's weeping would have begun in earnest with the ratification of the 16th and 17th amendment. These two amendments clearly ended the vision the Founding Fathers had for the Republic.
Does this observation cause you to ponder Americas future?
"The Roman Republic fell, not because of the ambition of Caesar or Augustus, but because it had already long ceased to be in any real sense a republic at all. When the sturdy Roman plebeian, who lived by his own labor, who voted without reward according to his own convictions, and who with his fellows formed in war the terrible Roman legion, had been changed into an idle creature who craved nothing in life save the gratification of a thirst for vapid excitement, who was fed by the state, and who directly or indirectly sold his vote to the highest bidder, then the end of the Republic was at hand, and nothing could save it. The laws were the same as they had been, but the people behind the laws had changed, and so the laws counted for nothing. Teddy Roosevelt on the Fall of the Republic
Huh...? Do we still have a constitution?
If it be asked, What is the most sacred duty and the greatest source of our security in a Republic? The answer would be, An inviolable respect for the Constitution and Lawsthe first growing out of the last... A sacred respect for the constitutional law is the vital principle, the sustaining energy of a free government. Alexander Hamilton

Very few established institutions, governments and constitutions... are ever destroyed by their enemies until they have been corrupted and weakened by their friends. Walter Lippmann
