Hey remember before the election happened, when Philadelphia was the focus of Trump's claims of that there would be massive voter fraud? That was when Trump expected to lose the election and thought Pennsylvania would stay blue. Now that Trump narrowly won state, his spokesman says that no voter fraud happened in Philadelphia. That fraud only happened in non-swing states that Trump lost bigly, like CA and NY.
(Which, if you think about it, would have been a remarkably bad strategy if democrats really had planned to use fraud to manipulate the election. If you're going to perpetrate a conspiracy to fraudulently alter a presidential election, wouldn't you target the swing states? Doing it only in safe blue states is a total waste of a nefarious plan.)
