Ok, time for me to get on a soapbox. Martin-Quinn scores are crap. They should not be used by journalists to measure SCOTUS ideology. Nor should they be used by scholars who don't understand their limits.

A quick thread explaining why... MQ scores look at one thing -- whether a justice voted to affirm or reverse in each case that they heard -- it then assigns these votes a "liberal" value or "conservative" value. So, for example, a justice who voted in the majority in Moore v. Harper gets a point for liberalism.

So in the likely event that Trump Judge Matty Kascmaryk bans mifepristone, here’s what we can expect next:

🧵 DOJ will seek an emergency stay from the Fifth Circuit as fast as it can review Matty’s opinion and draft a motion. They will likely lose. The Fifth Circuit is dominated by highly-partisan Republicans like Kyle Duncan.

So, obviously Leonard Leo did unimaginable harm to the United States through the Federalist Society. But I am skeptical he will be successful with this effort to expand the FedSoc model outside of the legal profession.

A quick thread explaining why...

The reason why the FedSoc is so powerful is because the pool of people who are plausible candidates for a Supreme Court seat is vanishingly small. Every single justice either graduated from Harvard or Yale law school, clerked on SCOTUS, or both.
