Amy Coney Barrett has officially been confirmed as a Supreme Court justice

In a narrow 52-48 vote, the Senate has officially confirmed Amy Coney Barrett for appointment to the Supreme Court, a huge win for Republicans who worked quickly — and ignored past precedent — to advance her nomination.

Barrett, who will now take the seat of the late Justice Ruth Bader Ginsburg, is a staunch conservative whose vote could be the deciding one on upcoming cases involving the Affordable Care Act, abortion rights, and voting rights. Her confirmation solidifies a 6-3 conservative majority on the high court, and is likely to affect its skew for decades.

Ultimately, every Republican senator except Susan Collins (R-ME) voted in favor of Barrett’s confirmation, while no Democrats did. Collins voted against Barrett because she disagreed with the process used for her nomination, something Democrats had objected to as well. Democrats had also expressed concerns about the conservative slant of Barrett’s past writings and opinions.
