I highly recommend G Elliott Morris' blog Strength in Numbers. He exists more in conversation with political science researchers and commercial polling professionals which makes his reporting feel a lot deeper and more interesting than the back of the envelope hot takes a bunch of other pundits try to sell as data journalism these days.

Strength in Numbers is very US politics centric, but Elliott also works with Mary Radcliffe on Fifty Plus One. That's a new hub for raw polling data (and averages) but they also do some broader polling roundup style stories that have a 538 feel.

David Nir of the Downballot is pretty good too if you are looking for information on the smaller races.

Outside of the SiN extended universe, Marist have a podcast called Poll Hub which is very light and fun and reminiscent of the cuddliest 538 podcasts before they started getting that weird contrarian podcast bro energy.

I've trialed a bunch of other sites since 538 went away and also checked in on the other alumni, but none of it outside of SiN-and-friends or the Marist quite hit for me.
