As others have said, we'll have a better idea in 2020. It could also be that it has shifted to the right, but that it won't continue to do so, and will just remain a Lean R state.

Virginia is blue, but people act like it's super dark Massachusetts blue when in reality the right GOP candidate could win it still. Gillespie could have won in 2014 if the GOP didn't pull out of that race.
Ohio will be a 5-7 point Republican state but still winnable for Democrats with the right candidate.
The 2017 Virginia gubernatorial race will be one to watch to see if VA is truly blue.
