For anybody who cares about this issue, it is congress' job to set the law. This issue has been bouncing around by executive order because all our legislators are so scared of being primaried that they won't actually write laws. Expecting our executive branch to do the job of the whole government is insanely problematic, including having our policy change at the drop of a hat. If you actually want real change, then you've got to let your legislators know what you want, you've got to hold them accountable, and you've got to not get all pissy when they actually have to compromise something else to get what is important to you. Then it isn't the end of the world when your opponent wins the White House and you don't have to rely on a partisan stacking of the supreme court to continue important policies.
