Reality Check

By way of demonstrating the impossibility of Hillary Clinton winning the Democratic nomination, here’s a scenario for the remaining contests.

West Virginia, Kentucky, Oregon: We’ll put Clinton in the win column 70/30.
Montana, South Dakota: We’ll project Clinton 52/48.
Puerto Rico: We’ll write in Clinton for a 60/40 win.
Superdelegates: Clinton picks up 64% of all remaining.

End Totals:
Clinton, 1993
Obama, 2026

The margins in WV, KY and OR are larger than anyone is projecting. The wins in MT and SD would be huge and entirely unexpected. And, Obama has been picking up superdelegates in nearly inverse numbers of this projection since February. So, under the worst case (Clinton wins all remaining primaries and a majority of undeclared supers), Obama still reaches the 2025 magic number.

In the real world, this thing is over.
