Denver Jewish Leaders Alarmed After Melat Kiros’ Primary Upset; Concerns Over Rhetoric and Rising Antisemitism

Melat Kiros, a 29-year-old Democratic Socialist, stunned Colorado in June when she defeated 15-term Rep. Diana DeGette in the Democratic primary for Colorado’s 1st Congressional District. While progressive groups celebrated the upset, many leaders in Denver’s Jewish community say Kiros’s rhetoric about Israel and her initial response to a deadly local attack have intensified fears of antisemitic hostility in the city.

Community Leaders Voice Concern

Local Jewish officials told Fox News Digital that statements by Kiros — including describing the Oct. 7 attacks as "inevitable," initially declining to label the Boulder firebombing as antisemitic, and characterizing Israel’s actions as tantamount to "genocide" and "apartheid" — have left many community members unsettled.

Rabbi Menachem Lehrfield, director of the Jewish Outreach Initiative in Denver, speaks about rising security concerns following Colorado's 1st Congressional District primary election in an interview with Fox News Digital on Monday, July 13, 2026.

Rabbi Menachem Lehrfield, director of the Jewish Outreach Initiative in Denver, published a social-media post and an op-ed describing how the climate in the city has shifted. After the primary, Lehrfield said he faced antisemitic replies online and, within 24 hours of his op-ed, was shouted at on the street. "I was walking down the street right here… and somebody rolled down their window and yelled, 'dirty Jew,' to me," he told Fox News Digital. "I don’t know what’s going to happen next time."

Melat Kiros participated in a League of Women Voters Congressional District 1 candidate forum at Montview Presbyterian Church in Denver, Colo., on May 28, 2026.

The Boulder Attack and Kiros’ Response

Many Denver residents remain traumatized by a June 2025 attack in Boulder, when an assailant threw Molotov cocktails into a peaceful pro-Israel gathering on the Pearl Street Mall. The attack killed 82-year-old Karen Diamond and injured about a dozen others. Prosecutors charged 45-year-old Mohamed Sabry Soliman with murder and hate crimes, saying he yelled "Free Palestine" and planned the attack to "kill all Zionist people."

When asked about that attack in a 9News interview, Kiros condemned the violence but initially declined to characterize it as antisemitic, saying she did not "know what was in the heart of the perpetrator." A few weeks later, she described the incident as "a horrific attack on a group of Jewish people that were peacefully protesting," while also saying Israel’s actions have contributed to rising antisemitism in the U.S. That mix of condemnation and structural critique has been a flashpoint for critics and supporters alike.

Advocacy Groups and Data

Susan Rona, regional director for the Anti-Defamation League (ADL) Mountain States Region, warned that political rhetoric can increase risk for vulnerable communities. "When political leaders refuse to name something as a targeted antisemitic attack, it creates distrust and additional fear because it minimizes and dehumanizes Jews, which can lead to violence," she told Fox News Digital.

Anti-Israel protesters gather at a "Stop the Sale of Stolen Palestinian Land" protest at the Park East Synagogue in Manhattan on Tuesday, May 5, 2026, in New York City.

The ADL reports that antisemitic incidents in Colorado rose dramatically, recording 167 incidents in 2025 — the third-highest annual total since the organization began tracking incidents in 1979. Advocates also say 2026 has seen a worrying uptick in violent episodes, including the Boulder firebombing and other assaults targeting visibly Jewish people.

Political Fallout and Varied Jewish Perspectives

Kiros’s campaign emphasized progressive domestic policies such as universal health care, housing reform, and expanded care for children and elders. Her campaign received endorsements from several progressive organizations, including the Democratic Socialists of America (DSA), Justice Democrats, and the Working Families Party.

Some Jewish community leaders say Kiros’s language normalizes dehumanizing rhetoric. Brandon Rattiner, senior director of the Jewish Community Relations Council (JCRC), said he met Kiros before the primary and felt betrayed when she later took more absolutist stances on an anti-Israel livestream. "A Jewish person was killed, over a dozen were hurt," Rattiner said, adding that the community deserves empathy and clear recognition of targeted antisemitic violence.

Other Jewish voices defend Kiros or call for nuance. Ian Zuckerman, an associate professor of history at Regis University, argued in an op-ed that rejecting political Zionism is not the same as antisemitism and praised Kiros for condemning violence against individuals. That split in opinion underscores broader debates over how criticism of Israeli policy intersects with concerns about antisemitism.

Electoral Consequences and Community Response

In response to Kiros’s victory, Jewish independent candidate Dr. Shimon Blau quickly gathered signatures to run in the general election; Republican Christy Peterson is also on the ballot. While the district strongly favors Democrats and Kiros is widely expected to win the general election, Blau’s campaign and other reactions illustrate real anxiety in parts of the Jewish community.

Despite tensions, some leaders remain committed to dialogue. "The Jewish community doesn’t want to be in a state of permanent warfare with any representative," Rattiner said. He urged Kiros to engage with the community, learn about the impact of rhetoric, and use her influence to help ensure concerns are heard rather than dismissed.

Note: Kiros’s campaign, Shimon Blau, and the DSA did not respond to Fox News Digital’s requests for comment.
