One updated projection (although assumes a few non-called races), has House coming down to the wire mostly in California which is one of the most extremely lagged states in handling election ballots. Note that not all ballots are even in the hands of elections officials yet in California - mail ballots must be accepted through Tuesday next week in California, if postmarked on or before election day.
Edit: Note CO-3 is Boebert, which I've pretty much written off now sadly. Republicans currently lead all 7 of these races, 3 with strong Republican leads including CO-3. Dems getting 4 of these would be an unlikely stretch, still looks like ~219-221 R's in House as most likely.
CA-13 within 100 votes, with only ~60% counted
CA-22 ~3k Republican lead (out of 60k), but only ~50% counted
CA-41 1.6k Republican lead (out of 130k), with ~60% counted
CA-3 is a stretch, 10k Republican lead (out of 170k), but only ~50% counted
CA-45 looks to be Republican, 13k R lead (out of 160k), ~70% counted
AZ-6 3k Republican lead (out of 300k), with ~83% counted
