In Minnesota's Fifth Congressional District, U.S. Rep. Ilhan Omar faces a Democratic primary challenger in a race where crime has emerged as the biggest issue. Omar's challenger, former Minneapolis City Council member Don Samuels, opposes the movement to defund the police and last year helped defeat efforts to replace the city's police department. Omar, who supported the referendum, has a substantial money advantage and is expected to benefit from a strong grassroots operation. *** On the Republican primary ballot, Cicely Davis and Royce White are seeking the GOP nomination.
