A sitting U.S. senator couldn't name a single place where socialism has been beneficial — and the press just let her walk away. That's the real story from Wednesday's CNBC interview with Delaware Sen. Lisa Blunt Rochester, who was asked point-blank where socialism has ever worked and replied, "Is that another question or is that for the next interview?"

This matters because the socialist wing of the Democratic Party just took a scalp — three of them, actually — in New York City's primaries. Brad Lander, Claire Valdez, and Darializa Avila Chevalier, all backed by the Democratic Socialists of America and endorsed by New York City Mayor Zohran Mamdani, defeated two sitting congressmen and a borough president's preferred successor. The DSA didn't just win; as the Daily Caller reported, they "took establishment, centrist Democrats out to the woodshed." And when a senator running to win back the Senate majority gets asked whether the ideology driving her party's newest stars has ever actually delivered results, she has nothing.

Blunt Rochester's full response to CNBC host Joe Kernen is worth examining. Asked about the socialist sweep, she celebrated "the fact that people are engaged" and insisted "politics are local," pointing to Alaska candidate Mary Peltola campaigning on "fish, family and freedom." When Kernen pressed — "Where has socialism ever worked, senator?" — she deflected. When he repeated the question, she deflected again: "Well, when you have me come back on we can talk about all the races across the country." Kernen then bailed her out entirely, calling it a "rhetorical question that I was answering myself."

That's not journalism. That's a favor.

The New York Post noted that all three winning candidates "campaigned on a socialist economic agenda, anti-Israel posture and opposition to Immigration and Customs Enforcement." The Daily Caller added that Israel was "a major focus of all the Mamdani and DSA-backed campaigns." Lander accused the Israeli government of committing genocide in Gaza — and won handily. Chevalier knocked off five-term incumbent Adriano Espaillat by five points. Rep. Dan Goldman, who stood by Israel, got kicked out of a Brooklyn coffee shop for his views and lost his ally in the process.

So the question isn't whether socialism is ascendant in the Democratic Party — it clearly is. The question is whether anyone in the press or the party's leadership will ever be forced to defend it on the merits. Blunt Rochester's dodge was telling: she couldn't point to Venezuela, Cuba, or the Soviet Union, because the record is a disaster. She couldn't point to Scandinavia, because those are market economies with generous welfare states, not socialist ones. So she said nothing, and CNBC thanked her for her time.

The Democratic establishment now faces a reckoning. The DSA is coming for their seats, and the moderates have no answer — not even a bad one. When the next socialist candidate wins a primary in your district, remember that the senator who's supposed to be leading the party couldn't name a single success story for the ideology now driving her base. The silence was the answer.
