There’s no need for that, unless parts of the US want independence, like some Scots regarding the UK. But break it all up because it’s too messy, not healthy? That’s what critics of the EU or the UN also say. Myself I’ve always been an advocate of unity and collaboration since it’s the only way we’re gonna be able to solve climate change and every other major world crisis.
Depends who you think of when you say status quo. I’d say the left is popular in many urban areas (radical left in modest neighborhoods and environmentalist/social-democrats for the rest), but the far rights reaps almost every rural area.
