General Discussion

The court has been shrunk/expanded before - from as few as 6 justices to as many as 10, all through congressional legislation.

The likelihood of expansion depends on two factors:
1) the awareness and motivation of the voters to select and elect candidates who support expansion, and
2) the courage of the elected officials to pass the legislation, especially the courage of those in the senate, who will need to kill the filibuster to pass court expansion.

To those who say we shouldn’t expand the court because the republicans will just do the same thing once they regain power, I say:

Democrats must never again govern out of fear of what republicans might do in retaliation.

After all, republicans never govern out of fear of what Democrats might do, do they?

If the court is expanded, and with the filibuster dead, Democrats ram through bill after bill restoring lost rights and repairing the damage of the Trump era, and then govern fearlessly, unhesitatingly and progressively for the benefit of all Americans (well except maybe the billionaires), it will be decades before republicans again have a chance to regain the trifecta of power, if ever.
