That would only work if the democrats were rational actors as a political party trying to maximize votes. Since 2016 they’ve made it clear that they want a party composed of certain kinds of people (lefties, Muslims, and men need not apply; war criminals from North Virginia highly encouraged to apply). They’re intentionally dumping the undesirables from their party in the hope they can win a GOP-style electoral college minority victory with the “right” people. They don’t want us. They don’t care if we vote or not.
