I just don't see it as a good solution to our problem when the Republicans will turn around next time and just appoint 20 conservative justices when they can. Maybe it at least buys us a few years of control that we otherwise wouldn't have, but it just seems like it is going to lead to more chaos.
This. Expanding the Court will just make things worse; b/c of current polarization, the Court will just expand w/ every new administration that takes office.
Plus, the problem w/ a perpetually expanding court is that it'll just be totally & completely partisan rather than a court of law, which leads to a weak court whose rulings (& the institution as a whole) are no longer respected by the people.
