It looks to me like Democrats/progressives/liberals are sitting pretty. The Republicans are down one Justice - let's call a spade a spade here - so as long as the seat remains empty the other side is that much better off. And ISTM that there's not much prospect that the next president will be Republican, and the Democrats may pick up a few Senate seats as well. So the smart Republicans may be well advised to get the best deal they can get now rather than putting it off. But the reactionary caucus will ensure that that doesn't happen.
