MI, CT, and ME should all be lean D. I'm still a little unsure about NM.
OK, AZ, TN, and GA should all be safe R.
OR should be safe D.
I'm also personally leaning towards MD being likely R.
Why in the world would AZ be safe R? That's nuts.
GA probably isn't realistic to call safe R either.
Ducey is pretty strong, and it doesn't seem like he'll attract a powerful opponent. Deal is also very popular, and I just don't see Democrats winning the governorship.
Most of Arizona's Democratic bench appears to be taking aim at Flake instead of Ducey.
