That’s a terrible idea. Even the deepest blue states have huge numbers of republicans/conservatives and even the deepest red states have huge numbers of democrats/liberals/progressives. It would do far more harm that good to split the country.
The US needs to balkanize I'm so fucking sick of fascist republicans. They need us more than we need their shithole states. We can have healthcare, immigrants, and a strong economy while they can keep cosplaying as nazis.
