Author Wes Moore has won the Democratic nomination for governor of Maryland.

Moore’s victory in the primary, which was held last Tuesday, was called by CBS News, NBC News, and the Associated Press. He beat several other candidates for the nomination, including former U.S. Secretary of Labor Tom Perez and Maryland Comptroller Peter Franchot.

Moore, an Army veteran and former charity CEO, made his literary debut in 2010 with The Other Wes Moore, a book that contrasts his life with that of another man with the same name; the two shared a similar background, but the other Moore became a drug dealer and robber who was convicted in the killing of a police officer. The book is being adapted into a film with NBA star Stephen Curry executive producing.

Moore’s other books include The Work, This Way Home (co-written with Shawn Goodman), and, most recently, Five Days (co-written with Erica L. Green), about the aftermath of the killing of Freddie Gray, the Black Baltimore man who died in a police van in 2015.

Moore celebrated his primary victory on Twitter, writing, “The stakes could not be higher, but together, we’ll meet this moment with urgency and leadership. Maryland WILL be a state where we leave no one behind.”

Moore enters the general election as a favorite in heavily Democratic Maryland. He’ll face the Republican nominee, Trump supporter and far-right state delegate Dan Cox, in November.
