What is happening in Pennsylvania? A trend, or back to normal?

[Starry Eyed Jagaloon]

There are two inverse trends happening at the same time. Non-SEPA is shrinking and getting more Republican, whereas SEPA is growing and getting more Democrat. The two trendlines crossed around 2016, with non-SEPA just winning out, but now everything is uphill for Democrats with a growing SEPA propelling them to ever larger victories. A similar trend could be seen in Virginia, if it were one state with WV. WV was ancestrally Democratic and would have once carried the state with Arlington and some downstate areas, but is shrinking and trending hard R. Meanwhile, NOVA is growing and trending hard D. The trends would have meant the GOP would win most elections in this combined state clear through 2016, but from 2018 on, growing NOVA will more than cancel out the rest of the fake state.
