The proximate cause of Carnahan’s departure was a firestorm that engulfed the party in recent days, after a GOP donor she was close to, Anton “Tony” Lazzaro, was indicted on federal sex-trafficking charges. A pile-on ensued, with Carnahan, the wife of Republican U.S. Rep. Jim Hagedorn, accused by party officials and former staffers of running a toxic, retaliatory workplace, mismanaging party finances and, through the use of non-disclosure agreements, squashing transparency.

“The party is in ruins,” Michael Brodkorb, a former deputy chair of the Minnesota GOP, said on Friday.

He added, “I don’t know if the party has hit rock bottom yet.”

There are reasons to think the party might not have. Even with Carnahan gone, Republicans are confronting what will likely be a monthslong slog of internal reviews and ongoing headlines about the saga — a drag on the party just over a year ahead of the midterm elections. In addition to the charges against Lazzaro, the chairwoman of the University of St. Thomas College Republicans was arrested on charges she assisted him in trafficking minors for sex, the Minneapolis Star Tribune reported.
