This is a challenging writing task.

Presidential biographies are a staple of children’s book publishing, and of classrooms across the country. Nonfiction for children is a surging category, particularly in light of a Common Core mandate that schools put greater emphasis on it in their curriculum. Publishers like Penguin Young Readers, Scholastic and Time for Kids chronicle stories like the rise of Mr. Obama from Illinois state senator to president, or the political legacy of the Bush family, interspersing those accounts with facts about presidential history. The books hit bookshelves every four years, usually long before historians and writers of nonfiction for adults weigh in. | But the story of Donald J.
