Most of the counties that still have 5-10% of the votes left to count, are areas where Biden isn't even getting 30% of the vote. Trump is set to get at least a couple thousand votes from nearly every county by the time counting is done. There's 67 counties in PA, and only 13 of them went for Biden, most of them at very close margins. Most of those are at 98%+ counted.

Even if Biden got 100% of the remaining votes in those counties that went for Biden, that still wouldn't be enough to counteract the combined and very likely remaining Trump votes in the other counties. Look at the PA county map! It's clear as day!

PA should have never been called for Biden, and no one can defend their reasoning for doing so once you look at the county map numbers!
