I doubt he'll be remembered as a great president. I voted for him twice on the grounds he was the better choice. Not a great choice. His greatest skill was surrounding himself with brilliant people and listening to them. Unfortunately, some of these brilliant people didn't have the country's best interests in mind.
I believe history will remember him for his abysmal monetary policy which included deregulation of commercial banking resulting in the financial melt down, the leader of the abrupt and sudden restrictions of personal freedoms after 911 by expanding powers of the NSA and other governmental control organizations to monitor and impede personal freedoms and finally as the president that undid the middle east by creating a power vacuum in a historically unstable region.
I'd place his legacy as a 20th century president somewhere between Hoover and Eisenhower, possessing Hoover's naivete of national and global financial matters and Eisenhower's disregard for personal liberties.
I believe the greatest Presidents of the last 100 years will be Truman, Reagan and F.D. Roosevelt, perhaps in that order.
