I have tremendous respect for David Blight's scholarship, but I question the wisdom of his advice that Joe Biden step down now so Kamala Harris can assume the presidency.
Invoking Lincoln doesn't make the advice any better - tho perhaps he thinks "be like Lincoln!" is more likely to sway Biden?
One of my favorite Lincoln-Hamlin interactions (there are so many!):
*Two months* after the 1860 convention, Lincoln wrote Hamlin to introduce himself: "Hey, I guess we're running together?! I don't think we ever met, but drop me a line when you can!"
