CA-21 is a lean Democrat. This is the best midterm wave for Democrats since Watergate.
Just imagine how we can reclaim ground with a bigger wave for 2020 redistricting and a strong progressive Democratic candidate facing a very badly damaged Trump facing impeachment/conviction trial. Even if Trump is not removed from office or if his approval is low to the point that he will be primaried, 2020 fundamentals favor the blueteam.
We can flip Senate seats of Arizona Colorado and Maine to gain a 50-50 tie with democratic vice president (maybe Mike Espy will make the requirement 2).
