The other thing this suggests to me is that if Dems do nonetheless win a trifecta in 2020, after taking care of the immediate/necessary COVID relief legislation etc, when they eventually start on policy legislation the first order of business should probably be immigration reform. Winning the sunbelt in the future is going to be very important for Dems in future elections, and so it is time to try and lock in more Hispanic support, and get more people on the pathway to citizenship and eventually voting in those sunbelt states (most importantly, Texas).
First order of business after COVID/stimulus is healthcare and police reform
