Democrat Pat Ryan on Tuesday won the Democratic primary for the newly drawn 18th congressional district in New York.

Why it matters: Ryan, who is also vying to finish the term of former Rep. Antonio Delgado, who left Congress to become New York's lieutenant governor in May in the neighboring 19th congressional district.

If Ryan is the winner of the special election in the 19th district, he will complete Delgado's term, which runs until the end of the year. He is facing off against GOP opponent Marcus Mollinaro in that race.

What we're watching: Ryan, the executive of Ulster County, shied away from the progressive label in an interview with Axios last month. Instead, he said: "I characterize myself as someone who's trying to level some of the foundational inequities we've allowed to be built in our country."
