A left-wing insurgent wave swept Colorado's Democratic primaries, a win for progressives and Bernie Sanders allies but a clear loss for the party's corporate establishment.

• Mati Curos, a democratic socialist backed by Justice Democrats and the DSA, crushed longtime Congresswoman Diana DeGette by more than 10 points.
• Her win would bring the number of DSA-affiliated members in Congress to seven.
• Similar upsets hit down-ballot races, with roughly 15 establishment Democrats losing to challengers on their left — dubbed a "Democratic Tea Party."
• Criticism of Israel and its war in Gaza became a litmus test, with insurgents casting establishment silence as corruption.
• Anger over local data centers and big-money politics helped drive turnout for the challengers.

Outlook: Expect the progressive insurgency to keep picking off establishment Democrats, fueled by independent media that didn't exist in past cycles.
