Buchanan could share the podium with Ozero, surely.
Surely not! Buchanan was a Conservative Democrat—had nothing in common with post FDR Northern Democrats. He was the victim of the Crash of 1857, which was not of his making.
Buchanen was a corrupt, weak and incompetent president very much like Obama. He oversaw mass treason towards the end of his administration when Confederates literally stole millions of dollars of arms and funds from the federal government and Buchanen helped them in some instances and did nothing in others.
However, he kept the government running on budget and did not pile up literally trillions of dollars of debt like Obama.
He also enforced the law and did not encourage and conspire with criminals.
Buchanen was a terrible president. But he was much, much better than Obama.
