Yes it would be. However a president does not have the power to do so. Only Congress can do so. Let’s take a look at the two possibilities that exist to expand the court. Trump wins and has majorities in both houses. Attempting to expand the court would be a minor power grab compared to the other plans he has. I doubt he’d waste his time, he already has a rubber stamp court. If Biden is in the same position, it’s easy to justify expanding the court by two members. I’d say Democrats should do four just to make sure. That along with getting rid of the filibuster, passing a new voting rights act and passing the border bill, single payer health care, a one time wealth task, income tax reform, entitlement reform, codifying Roe v. Wade, passing protections for the LGBTQ population, and strengthening consumer and environmental protections. That should fix a lot of the damage.
