In the next two years I could see Arizona, Minnesota, and Virginia flipping to Dem trifectas.
Texas House and Florida Senate should both be in play for 2020 as well.
Other than that I don't see much changing (Not sure about North Carolina's legislative chambers...?).
Ducey is the governor, so it can't flip to a Democratic trifecta.
IMO the Dems have a good shot in 2020 at flipping the AK House, AZ House+Senate, FL Senate (crucial for redistricting), IA House, MI House, MN Senate, NC House+Senate, PA House+Senate, TX House, and WI Senate, and can conceivably break R supermajorities in the OH House and the KS House.
