A sample of 525 historians have ranked Joe Biden 14th on the annual “Presidential Greatness Project Expert Survey” run by Brandon Rottinghaus at the University of Houston and Justin Vaughn at Coastal Carolina University, putting the current commander-in-chief behind Lincoln in first place, FDR in second, Obama at 7th, and ahead of Reagan at 16th, Carter at 22nd, and George W Bush at 32nd. You’ll never guess who’s last, behind even James Buchanan and Andrew Johnson.
