There are a few straggling districts which are safe for one side or the other and the outcome is not in doubt, but the votes are being counted slowly and there are not enough returns in yet to feel like they can make the final call. Most trackers will not count them on the top line yet, but when they report the number of sets left to claim the majority, they will assume those seats are safe.
In general, though, Republicans have enough leads in enough races that if somehow Democrats win all the races where they are currently leading and the races where a Republican is currently leading by < 1%, Republicans will still retain control of the chamber, albeit with even slimmer margins than last time.
