He WILL need to distinguish himself from his brother, the worst President of the United States since at least Andrew Johnson. He WILL have to explain how he creates a sustainable prosperity without some speculative boom that devours capital and then goes bust. He WILL need to tell us how his foreign policy will differ from that of his brother's disaster.
He will surely surround himself with the neo-liberal types who trivialize the misfortune of anyone not already super-rich. He will likely find his staff on military and foreign policy among neo-con chickenhawks.
Andrew Johnson was president in the 1860's, the worst president since then is Hoover, not W. Bush.
