PROVIDENCE, R.I. (WPRI) — General Treasurer Seth Magaziner has won the Democratic nomination for Rhode Island’s 2nd Congressional District, according to unofficial results, setting up a marquee fall matchup against Republican Allan Fung.

Magaziner defeated multiple other candidates to win the nomination.

The 2nd District seat is open due to the unexpected retirement of longtime Democratic incumbent Jim Langevin. Magaziner had originally been running for governor but last January opted to switch races and seek Langevin’s seat instead.

The only public poll released for the November election in the 2nd District showed Fung leading Magaziner as of June. National forecasters have said they expect the race to be competitive.

Sarah Morgenthau, one of the Democrats vying for the seat, conceded the race Tuesday night.

“I spoke on the phone with Treasurer Magaziner earlier and congratulated him on his victory,” Morgenthau said. “As I have said before, the most important thing is that we keep this seat under Democratic control, the stakes are simply too high. I have assured the Treasurer that I will do everything in my power to ensure that is the case, and to support his campaign in the months to come.”
