One thing I've done, I created a "Short List" column of a subset of "My Friends" I particularly want to follow. You could curate a small enough group there who tag their political posts, and ignore the other columns when you-can't-even-anymore.
Doesn't work on a phone, unfortunately.
@EileenKCarpenter I can just about make it work on a phone and I think I will do that. It's not *convenient* but it's doable. Thanks for the reminder xx
