Throughout the Cold War, conservatives loved to accuse liberals of being socialist (or communist, Marxist, Stalinist, etc). One would think that those accusations would have disappeared after the collapse of the Soviet Union, but they haven’t. They keep going back to that well time and again, and almost always in the most wildly inaccurate ways. Mitch McConnell gives a textbook example:
They plan to make the District of Columbia a state — that’d give them two new Democratic senators — Puerto Rico a state, that would give them two more new Democratic senators. And as a former Supreme Court clerk yourself, you’ve surely noticed that they plan to expand the Supreme Court. So this is full bore socialism on the march in the House. And yeah, as long as I’m the majority leader of the Senate, none of that stuff is going anywhere.
And no, they don’t plan to expand the Supreme Court. A couple people have suggested it, but they’ve gotten no traction at all. And there’s no way such a policy would pass anyway. Fearmongering over nothing, the right’s modus operandi.
