It's just a talking point that gets repeated by folks that don't follow the legal profession in general or the federal courts more specifically. It's completely ridiculous to claim that Barrett is a "conservative sockpuppet" as some commenter below us makes. She's been a law professor most of her life. But everyone plays dirty: Garland should've been on SCOTUS (his work on the OKC bombing prosecution speaks for itself, and is not to mention patriotic); it's a shame that Congress blocked that vote, but politics is politics.
