Watch: Surging Dem candidate's one attack that drew 30-second standing ovation

Graham Platner, the Democratic hopeful in Maine looking to unseat Sen. Susan Collins next year, received the largest applause of his Labor Day speech in Portland on Monday when he railed against the ill-spent taxpayer money used to support the Israeli genocide in Gaza—a sharp contrast with many in the party who have shied away from such direct criticism of Israeli's assault and the backing it receives from the US government.

Even as support for Israel's assault on Gaza has plummeted among US voters and Americans across the political spectrum have increasingly demanded an arms embargo on the country, a number of Democratic politicians have struggled to keep up with the electorate in recent weeks.

Former Transportation Secretary Pete Buttigiegcalled the conflict in Gaza that's killed more than 63,000 Palestinians and starved hundreds of people "complicated," while Rep. Ritchie Torres (D-NY) last week accused a Jewish comedian of "justifying antisemitism" for noting that more than 80% of people killed by the Israel Defense Forces were civilians. Both responses garnered condemnation from Palestinian rights advocates and progressive commentators.

But on Monday—before a packed house of more than 6,500 in Portland—Platner took a much different approach.

"Our taxpayer dollars can build schools and hospitals in America, not bombs to destroy them in Gaza," said Platner, leading the audience to stand up and applaud for a full 30 seconds.

Platner, a military veteran and oyster farmer who is challenging Collins—a vehement supporter of Israel—has previously spoken about Gaza in an interview for Zeteo, calling Israel's US-backed attack on the territory "the moral test of our time."

He repeated his message on social media Tuesday, saying: "It's not complicated: Not one more taxpayer dollar for genocide."

Platner was speaking at a rally hosted by Sen. Bernie Sanders (I-Vt.), as part of the senator's ongoing Fighting Oligarchy tour—a project that some establishment Democrats have claimed is out of touch with the views of Democratic voters even as Sanders has filled arenas in both red and blue districts across the country.

Rep. Eliss Slotkin (D-Mich.) has claimed the term "oligarchy" is unfamiliar to Americans, but the audience of a reported 6,500 people in Portland evidently didn't have trouble understanding Platner when he named oligarchy as "the enemy" of working Americans.

The line also garnered a standing ovation.

"I've been waiting my entire life," said journalist David Sirota, "for a politician other than Bernie Sanders to just say this."
