Tell them goodbye, and tell them to say goodbye to social security checks, military retirement checks, medicare, federal aid of every sort and demand repayment for federal dollars already spent in the state.

Use the West VA example to admit them or keep them in the Union and be ready for more Republicans in DC.
All those federal outlays are pay-go now. So the taxes that Californians were paying to DC to fund that stuff will just now go to Sacramento. Same same.
