Obama had 8 years in office. The debt went from $10 trillion to $20 Trillion. Trump will move it from $20 to $28 trillion in the same 8 years. And that is with more debt and the Fed raising the rates on that debt. If the Fed cuts rates back to about 1%, Trump will cut a trillion out of the debt over 8 years in office.
No the debt would remain the same but the cost of servicing that debt may go down.
