You’re not wrong."Half the country" doesn't view it was such.
I daresay that the vast majority of the country has no conception of what the Supreme Court does, and are completely unaware of the shift in SCOTUS ideology.
It will continue to function as the final arbiter of cases involving federal law or within its original jurisdiction.
The last 20 years, particularly after the SCOTUS' erroneous decision in Bush v. Gore and subsequent Congressional infighting and refusal to honor unwritten rules regarding nominations - have accelerated the need for a return to some kind of balance.
It's the GOP's creation of the circumstances that necessitate this.
But I disagree with packing being necessary.
The sky isn’t falling.
