AOC endorses Sen Ed Markey as incumbent faces Dem US Senate primary challenge from Rep Seth Moulton

So AOC is throwing her weight behind Ed Markey, a 79-year-old senator who has been in Washington since the Reagan administration, over Seth Moulton, a Marine veteran who actually served in Iraq. If you wanted a snapshot of what the Democratic Party has become, this is it. The progressive wing isn't rallying around new blood or a moderate who might actually appeal outside deep-blue Massachusetts. They're circling the wagons around incumbency and ideological purity.

Moulton has made a habit of saying things Democrats aren't supposed to say out loud, about parental rights in schools, about the border, about the party listening to voters instead of activists. That's precisely why AOC is stepping in now. This isn't really about Markey's record. It's about making sure nobody who threatens the progressive consensus gets a foothold, even in a primary most of the country will barely notice.

Markey has spent nearly five decades in Congress. The idea that a 33-year-old congresswoman is now a kingmaker deciding who gets to keep that streak going tells you where the actual power in that party sits. It's not with voters weighing candidates on merit. It's with a small, loud faction protecting its own.

Massachusetts Democrats will sort this out themselves, and maybe Moulton doesn't have the juice to pull it off anyway. But the instinct on display here, closing ranks against a war veteran because he occasionally thinks for himself, says plenty about a party still more comfortable with orthodoxy than with independence.
