The only state were we can really predict the 2020 maps in Virginia - and that is after the November elections. Then, we will see who controls the Governor and the General Assembly, and what the trendline in the HoD is and can it flip/remain R in time for 2020.
Not necessarily. This time it is a little bit tricky for Democrats in Virginia. There are a few options here:
1. Democrats have to win Gov race both this year and in 2021, ensuring veto power over maps no matter when Republicans do it. Republicans will surely punt the redraw to 2022 if Gillespie loses this year.
or
2. Democrats win a state Senate majority in 2019 and prevent any defections or retirement enticements from the GOP. This allows a veto of a Congressional gerrymander and legislative maps, although a bipartisan gerrymander is a fair bet for the legislative maps.
3. The rarest option - Democrats somehow win a trifecta by 2021 by holding the gov this year and handing heavy losses to the HoD Republicans, winning the state Senate in 2019 and building on HoD gains, and then in 2021 finally win a bare majority while holding the Govs office. Again, this still seems unlikely, even if they get a new HoD map due to the racial gerrymandering lawsuit currently pending.
Either way, the VA Democrats' redistricting situation will not be solved by the 2017 elections alone.
