For a good while into the second Donald Trump presidency, centrist Democrats were nowhere to be found. Their strategy was, in the immortal words of former Bill Clinton campaign strategist James Carville, to “roll over and play dead” and simply wait and hope that the Trump administration would collapse in popularity without them having to do anything.

A year and a half later, Trump’s approval rating is in the toilet, some of the most divisive primary contests are over, and there are only three months to go until the midterm elections that may well decide not just the future of Trump’s presidency but the entire country’s political trajectory. So the average Democratic voter will be heartened to learn that — as the smoke clears after the bitter Michigan primary contest and its two rival Democratic candidates make up and vow to join forces for the general election — centrist Democrats have suddenly come back to life, gearing up to wage relentless war against their political opponents to the tune of $15 million.

No, not Republicans. The political opponents that have the centrist Democrats newly energized and willing to fight like hell are the democratic socialists who have become a powerful organizing force within their party and some of its most popular national figures.
