The fine folks at My Daguerrotype Boyfriend are celebrating President's Day the only appropriate way: by posting pictures of our hottest commanders-in-chief. Clockwise, from top left: Teddy Roosevelt (during his time rowing crew at Harvard); Teddy again, as a Harvard freshman; William McKinley as a Union soldier in the Civil War; Rutherford B. Hayes; Abraham Lincoln's son Robert Todd; and a 16-year-old James Garfield. Feel free to post your own presidential favorites in the comments.
