The former Democratic National Committee chair appeared on ABC’s This Week and delivered a remarkably candid assessment of the ideological battle unfolding inside her party.
“The Democratic Party must define itself and make sure that we don’t get caught in this socialist wave,” Brazile told George Stephanopoulos.
That warning comes as candidates aligned with the Democratic Socialists of America continue scoring victories in Democratic primaries across the country.
Socialists Are No Longer Knocking on the Door
For years, establishment Democrats could dismiss democratic socialism as the domain of Bernie Sanders, Alexandria Ocasio-Cortez, and a relatively small collection of progressive activists.
That argument is becoming increasingly difficult to make.
DSA-backed candidates have reportedly captured more than 30 Democratic primary victories during the 2026 election cycle, with successes stretching from New York to Colorado, Michigan, and Wisconsin.
One of the biggest political earthquakes came in Colorado.
Melat Kiros, a 29-year-old graduate student, defeated longtime Rep. Diana DeGette in the Democratic primary for Colorado’s 1st Congressional District.
DeGette had represented the Denver-based district since 1997.
Her defeat offered another sign that longevity, establishment connections, and institutional support may no longer protect Democratic incumbents from challengers running aggressively to their left.
New York has produced similar warning signs.
Three DSA-supported congressional candidates won Democratic primaries there on the same night, including challengers who knocked off incumbent lawmakers.
And hovering over the socialist movement’s expansion is New York City Mayor Zohran Mamdani.
After campaigning for DSA-aligned candidates, Mamdani made clear that he sees the movement as having national potential.
A democratic socialist can win “anywhere across this country for any position,” Mamdani declared.
The movement apparently intends to test that theory.
The DSA has voted to pursue a presidential campaign in 2028, potentially turning what was once an insurgent faction into a national political operation.
Ocasio-Cortez has inevitably emerged in political speculation about who could carry that banner.
The Democratic Base Is Changing
Brazile’s comments are particularly significant because this fight is not merely taking place among politicians.
The Democratic electorate itself appears to be shifting.
A CNN poll released this week found roughly one-third of Democrats and Democratic-leaning independents identifying as democratic socialists.
That creates a serious dilemma for party leaders.
Democratic officials can distance themselves from socialism rhetorically, but doing so becomes considerably harder when socialist candidates repeatedly defeat establishment Democrats in their own primaries.
The policy differences are also substantial.
DSA priorities include Medicare for All, dramatically higher taxes on wealthy Americans, major changes to U.S. foreign policy regarding Israel and the Palestinians, and experiments with publicly operated grocery stores.
Those positions are far removed from the centrist image Democrats cultivated during the Bill Clinton era.
The question now facing party leaders is whether they still have the political strength—or even the desire—to push back.
Establishment Money Isn’t Stopping the Left
Perhaps the most revealing part of the socialist surge is that establishment forces have already tried using one of Washington’s favorite weapons against it: money.
It hasn’t necessarily worked.
Outside groups poured millions of dollars into New York races in an attempt to stop DSA-aligned candidates.
Socialist-backed contenders nevertheless continued winning.
Mamdani’s own rise exposed the same weakness.
Major Democratic figures were initially reluctant to embrace him.
New York Gov. Kathy Hochul withheld her endorsement during his campaign. House Democratic leader Hakeem Jeffries also held back before eventually moving closer to Mamdani politically.
Senate Minority Leader Chuck Schumer similarly avoided becoming an enthusiastic champion.
Yet hesitation is not opposition.
The Democratic establishment never managed to build an effective firewall capable of stopping Mamdani or the movement growing around him.
Now he occupies one of the most influential political offices in America and is helping other socialist candidates challenge Democrats across the country.
Republicans Could Not Have Asked for a Better Opening
For decades, Republicans have accused Democrats of drifting toward socialism.
Democrats routinely dismissed the charge as Republican campaign rhetoric.
That defense becomes harder when candidates openly running as democratic socialists are defeating Democratic incumbents.
Republicans no longer have to invent the label.
The candidates themselves are embracing it.
That could become a major vulnerability heading into the midterm elections and eventually the 2028 presidential contest, particularly in swing districts where voters may be considerably less enthusiastic about socialism than Democratic primary voters in deep-blue cities.
Brazile clearly recognizes the danger.
But telling Democrats to “define” themselves may be easier than actually doing it.
The party’s old guard can issue warnings on Sunday television programs. It can spend millions trying to protect incumbents. It can cautiously distance itself from socialist candidates during primaries.
None of that matters if Democratic voters keep choosing the insurgents.
The central question is therefore no longer whether democratic socialists can influence the Democratic Party.
They already are.
The real question is how much of the party they can capture before establishment Democrats decide to fight back—and whether, by then, it will already be too late.
