This wasn’t a Republican beating a Democrat.
It was the left moving further left.
Melat Kiros defeated 15 term Representative Diana DeGette in Colorado’s 1st Congressional District 51% to 42%, ending the career of one of the House’s longest-serving progressive Democrats.
That’s what makes this race so interesting.
DeGette wasn’t a centrist.
She was a member of the Congressional Progressive Caucus and had represented Denver for decades.
Yet that wasn’t enough for today’s Democratic primary voters.
Kiros was backed by the Democratic Socialists of America and Justice Democrats, campaigning on policies including Medicare for All, abolishing ICE, and stronger support for Palestinians.
I get what you mean here, but saying "the socialists" will have the "new ideas" is like saying "the Shakers have all the fresh thinking." Socialism is not new. The label is about 2 centuries old, give or take. The idea is thousands of years old. There's not a single major idea… https://t.co/e3tqtK9PQP

The pattern is becoming harder to ignore.
The biggest fights inside the Democratic Party are no longer between moderates and progressives.
They’re increasingly between progressives and democratic socialists.
That’s also why debates over issues like rent freezes, government intervention, and other socialist policies are becoming more prominent.
Ideas that were once mostly discussed on college campuses are now deciding congressional primaries.
Whether those policies ultimately succeed or fail is a separate debate.
The political shift itself is the story.
A candidate considered solidly progressive a few years ago just lost because many primary voters wanted someone even further to the left.
That’s a warning for every incumbent Democrat.
In today’s Democratic primaries, being progressive may no longer be progressive enough.
Wobblies tossing bombs at Pinkertons, Pullman Car workers singing Woody Guthrie tunes, wildcat strikes at waistcoat factories…
Yeah, that century-old Industrial Age Utopianism is filled with “new ideas.” https://t.co/CXURg7A1vr
