142 presidential historians surveyed by C-SPAN

[David Lockmiller]

Even with all the new historians participating, the top and bottom rankings remained unchanged. Since 2009, the top four presidents have been: 1) Abraham Lincoln 2) George Washington 3) Franklin D. Roosevelt and 4) Theodore Roosevelt. (Washington and FDR switched places in the 2000 survey.) The bottom three have been always been Pierce, Johnson and Buchanan, in that order.

Note: Buchanan and Johnson presidential terms bookend that of President Lincoln.
