I was listening to Nate Silver today and he had some interesting thoughts on Nevada. He says he could call it now. Biden is ahead, all the remaining votes to be counted are from Democratic strongholds around Las Vegas and those have been breaking 70+% Biden, from a statistical point of view, Nevada could be called, there is not a reasonable statistical path for Trump there. But calling Nevada is calling the election. (He's confident that PA will go Biden for the same reasons.) There is already some angst around the call of Arizona. Calling either Nevada or Pennsylvania is calling the whole shebang and no one is willing to do that.
