Harris, who is also pretty moderate

Pretty moderate by imperial standards. Absolute fascist by objective measurement.

I doubt that moderate Democrats are especially upset at the moment.

Ofc most dems are not upset. They’re completely fine with 99% of Trump’s fascism. That’s why we’re here.

The second problem is that the US electoral system always stabilizes around two big-tent parties.

AKA it’s an excellent system for violent control but a terrible joke of a “democracy”.

It’s not clear to me that introducing a new party solves problems here.

They’re not trying to solve problems that we care about. They’re trying to maintain their control. That’s the “problem” here.
