Let's see, George W. Bush added 5 trillion after 8 years in office, Obama added 10 trillion after 8 years in office, and Trump has added 2 trillion after 3 years in office. He stands to do less damage than even Bush if he keeps the pace, and the problem with that much debt is it further accelerates the debt from just the interest alone. If it were only 10 trillion when Obama left office there's a good chance he could have kept it from increasing from that after 3 years.
