What AIPAC is doing here is they see a vulnerable member they don’t like on their issue and they go after them," said a House Democrat.

The lawmaker added: “Whatever you think of [AIPAC], they’re pretty intelligent. They’ve got some skin in this in the sense that if Bowman wins, that’s egg on their face. They’re very strategic.”

This is how moderates act when a progressive incumbent loses…

But if it’s a moderat incumbent, even as shitty as Manchin, the DNC protects them, and untill very recently opened threatened to blackball anyone that came close to a primary campaign against any incumbent.

Any “party unity” has always been one sided. “Moderates” prefer republicans to progress.
