Blockchain will only determine fake ballots. There are far more ways to do voter fraud, including using real ballots. In Wisconsin, they altered thousands of ballots knowing what they were doing was illegal. In Nevada there are thousands of out of state voters. In PA hundreds of thousands of mail in ballots are invalid since they did not arrive at the county office by 8PM election day. Those are only some of the things coming up that will flip those states.

The media does not determine the winner or if something is evidence or not. They can ignore it all they want. This is all going to the courts.
