Your background to challenge common sense is exactly what? If you think the US Supreme Court is going to throw out a national election based on some witness testimony prepare for disappointment.
If you think the US Supreme Court is going to invalidate tens of thousands of mail in votes based on the changing of PA election law through judicial fiat you are on firm ground. Similar deal in GA. That is clear unconstitutional activity.
Again what is your background?
You did not answer the question, therefore, I deem your testimony is as non responsive.
