From what I’ve seen, it’s Arizona and Nevada
The count is 264 including Arizona. AP has been including Arizona since early Wednesday morning. Nevada’s 6 would clinch the 270 needed. They said they will release info at noon Eastern (9am Pacific).
Most outstanding ballots in Pennsylvania are from the Philadelphia area. There is a very good chance they will give Biden the win.
Georgia is still possible. It is going to be super-close either way.
