Not even close. Recently we have the Bush 2 years, when companies like Halliburton and Blackwater exchanged campaign contributions for military contracts the army could have performed cheaper, although they are hard to put a number on because there haven't been enough details revealed to estimate an accurate total. For those time has been able to expose there are some much better nominees. Warren Gamaliel Harding, for example, was personally corrupt and brought his cronies into Cabinet with him so they could get theirs as well. Secretary of the Interior Harry Daugherty was the worst. He was convicted of selling the Teapot Dome National Oil Reserve in exchange for bribes that John D. Rockefeller was acquitted of paying. Harding would most certainly have been impeached had he not died in what is believed to have been a suicide. These are both Republicans, but the Democrats offer us James Buchanan, who allowed his southern Cabinet members to transfer arms and manufacturing equipment to their home states in preparation for Secession, then did nothing when they did secede because he needed their support at the nominating convention to keep his rival Stephen Douglas from gaining control of the party. We can offer Hiram Ulysses Grant's administration as a reasonably honest President surrounded by wolves. Barack Obama was actually fairly ethical and fiscally responsible, although every administration of every party has its problem people. I think I have to go with Buchanan as the worst, because he knowingly violated his Inaugural Oath and ignored literal treason for personal gain.
