I'd rate Obama 3rd worst behind FDR and LBJ. FDR was even more of a dictator than Obama. Thankfully, the SCOTUS put a stop to FDR's National Recovery Administration; so he set to work to try to pack the court and remove them as an obstacle. He managed the economy so badly it is remarkable that it ever rebounded. LBJ created the welfare state, and Obama ruined the healthcare system. There may have been more incompetent boobs in office; but these three had the most lasting negative effect. Between the three of them, they have essentially destroyed the country.
