Reply #41: Buchanan is unquestionably the worst president the US has had.

[Spider Jerusalem]

His incompetence, indecisiveness, and blatant stupidity led to the Civil War. He illegally contacted an acquaintance on the Supreme Court (separation of powers, you know) before he was actually inaugurated and convinced him to vote the pro-slavery side in the Dred Scott case; he completely bungled the issue of slavery in the territories (accepting Kansas' illegitimate pro-slavery Lecompton Constitution); he was a weak-willed fool who thought that secession was unconstitutional, but that he hadn't the authority to prevent it...Bush is bad, but he's nowhere NEAR as bad as Buchanan. Not yet, anyway. (He still has three years to go, though.)
