During his recent visit to the U.S., Ukrainian President Volodymyr Zelensky quoted Abraham Lincoln, saying that Ukraine’s army would follow the instructions that Lincoln once gave a general—to “chew & choke” the enemy. Zelensky was observing America’s bipartisan tradition of invoking Lincoln. Barack Obama launched his first presidential campaign at the Illinois statehouse where Lincoln served, and Donald Trump staged a Fox News interview at the Lincoln Memorial. Some of Trump’s Republican critics run a PAC called the Lincoln Project, and President Biden quoted Lincoln in his inaugural address.
