538 on Moore v. Harper:

The independent state legislature theory is fewer than 25 years old, and for most of its life, it’s been relegated to the fringes of academia. But it was widely promoted by former President Donald Trump and his allies as they attempted to first undermine — and then overturn — the outcome of the 2020 presidential election. And several Supreme Court justices have already suggested that they’re on board with the theory. During litigation over election laws in Pennsylvania and Wisconsin in 2020, Justices Clarence Thomas, Samuel Alito and Neil Gorsuch endorsed some version of the idea that state legislatures should have nearly unfettered power over how federal elections are run, and earlier this year, they said in an emergency-docket ruling that they would have ruled in favor of the North Carolina legislature.
