In looking for Presidential materials I found that Abraham Lincoln plays a major role in one of the DC Elseworlds' titles, "Superman, A Nation Divided." Here's a segment where Superman, a Union soldier saves Lincoln's life
About this title:
Young Atticus Kent learns of his powers and abilities, and helps the Union Army win the war, saves the life of Abraham Lincoln and goes on to bigger and better things.
Elseworlds is the publication imprint for a group of comic books produced by DC Comics that take place outside the company's canon. According to its tagline: "In Elseworlds, heroes are taken from their usual settings and put into strange times and places - some that have existed, and others that can't, couldn't or shouldn't exist. The result is stories that make characters who are as familiar as yesterday seem as fresh as tomorrow." Unlike its Marvel Comics counterpart What If...?, which bases its stories on a single point of divergence from the regular continuity, most Elseworlds stories instead take place in entirely self-contained continuities whose only connection to the canon DC continuity are the presence of familiar DC characters.
