ANNAPOLIS, MD (AP) – It’s primary election day in Maryland today. Both Republicans and Democrats have competitive primaries for governor this year to succeed the term-limited Republican Gov. Larry Hogan. Katie Curran O’Malley, a former Baltimore judge and Maryland first lady, is running for the Democrat nomination to an office that will be opening with the retirement of Attorney General Brian Frosh. She is running against U.S. Rep. Anthony Brown, who was lieutenant governor during the administration of former Gov. Martin O’Malley, Curran O’Malley’s husband. For the GOP, former prosecutor Jim Shalleck is running against Michael Peroutka, who served a term on the Anne Arundel County Council. Polls in Maryland are open until 8 p.m.
