Are you incapable of reading first the chart you provided?

Democrat Kennedy left the country in better shape then he got it in and left it in a positive trajectory. 

Republican Nixon and Ford added more debt.

Democrat Carter was close to neutral though added a minor amount of debt.

Republicans Regan and Bush added a huge amount of debt.

Democrat Clinton did what no other president has done on the modern era:
He brought us out of MASSIVE debt into savings. 

Republican Bush DESTROYED the economy and gave us crippling debt.

Democrats are neutral or pay off debt, republicans have added huge amounts of it and left the economy in shambles often.
