Might be time for a conversation with them? not now, but when things settle down a bit. They may not be aware of this cycle, but if they are it might be a good opportunity to point out you wont always be able to support them when they (find a nicer way to say shoot themselves in the foot for the 10th time in a row).

take care of yourself too. No harm in taking a step back from other folks drama. I had to do something similar when mates tried to involve me in their marital disputes. “nah guys, got enough drama myself without adding yours, thanks!”
