I like reading the investigative stories at Talking Points Memo's Longform section (http://talkingpointsmemo.com/longform http://talkingpointsmemo.com/longform), and I'm also a fan a lot of the original work at Pando (https://pando.com/ https://pando.com/). I tend to follow the source links on a lot of the more popular sites and see if the original is worth a RSS subscription.
