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...?).
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.
There appears to be no LG tiebreaker in Florida, so they should only have to tie it to get a say in redistricting. That, along with MN Senate, TX House, and 1/3rd of the KS House (plausible to do this now by getting more suburban R party switchers) should be the top priorities. NC House and GA House are worth a strong effort as well because a say in redistricting in either state would be so valuable, but the odds of actually flipping control are long. I wouldn't say chambers where there is both an R governor and an independent redistricting commission are worthy of as much effort.
North Carolina's Sate Supreme Court is gonna make the help things out there as well.
