The real "why isn't the race called?" story isn't PA.

Nevada's a wrap, as @RalstonReports makes clear. If Fox called NV for Biden, that's 270 on their map, because they've stuck w/ their AZ call.

They'd be declaring Biden president-elect... and alienating some powerful people.

FWIW the Associated Press called Arizona the other day too... less corporate intrigue there, though probably the same gun-shyness when it comes to calling Nevada... not because NV isn't a sure thing, but because of how the numbers tightened in AZ.

Not taking sides here.... 270 is 270 is 270.... but clearly some folks believe calling the presidency is a higher bar than calling an individual state, because right now, calling an individual state is ipso facto calling the presidency.
