I’m referring to this, in the article.
The conservative justices appointed by his rival, former President Donald Trump, are “already gutting voting rights, overturning Roe, decimating affirmative action, and so much more,” Biden said. “Are we going to let that happen? We can’t.”
The Democrats are, in fact, letting it happen.
The Supreme Court idea of judicial review was, essentially, created by an early Chief Justice using the classic children’s excuse “the rules don’t say I can’t do this so therefore I’m doing it and you can’t stop me”
Edit: I had this somewhat wrong. After reading, it seems a lot of the people who wrote and debated on the Constitution wrote strongly in support of judicial review, and it was in fact voted on and approved by multiple state legislatures after the Constitution was adopted. It simply wasn’t worded explicitly into the Constitution. Chief Justice John Marshall did issue an official ruling that made it a standard practice but it was not a new concept.
