...Grahame-Smith’s vision of Abe Lincoln, the most iconic of American presidents, moonlighting as a merciless vampire hunter is satisfying for many reasons, chief among them the security implications. Action movies continuously imagine presidents with Bourne-level reflexes and Bondian smarts, but they pale in comparison to the general badassery Lincoln is revealed to possess is this twisted secret history. Seeing a candidate go ax-crazy on live television after a horde of undead bursts in to violently protest your party platform would certainly be a game-changing moment in American politics—and a much better reason to vote for someone than their snooze-worthy tax policy
