Judge rules in N.C. Attorney General Josh Stein's favor

• In a complaint filed with the state board of elections, O'Neill argued that an ad Stein's campaign ran violated that law.

Driving the news: The complaint triggered a criminal investigation. Attorneys representing Stein's campaign argued in court yesterday that the law at the center of that investigation is unconstitutional.

• In a lawsuit first reported by the News & Observer, Stein called the law "archaic" and said it had never been used before.

Why it matters: The ruling is a win for Stein, who is both the state's top law enforcement officer and the second most powerful Democrat, after Gov. Roy Cooper.

• Stein could have faced prosecution for violating the law had the judge not issued a temporary restraining order on the law.

The intrigue: The investigation is now in the hands of Wake County District Attorney Lorrin Freeman's office. Freeman, who is also a Democrat, has recused herself from the case, the N&O reported.
