The field of candidates vying to become Delaware’s next attorney general has been set, after former Sussex County chief prosecutor Peggy Marshall Thomas this week filed as the only Republican seeking the post.

Thomas, who served in the Department of Justice for three decades, officially entered the race on Monday, one day ahead of the state filing deadline. Unopposed on the Republican side, she joins a crowded field of Democrats hoping to succeed Matt Denn, who announced last year that he would not seek re-election in November.
