Why don’t you ask yourself this question. Why would a political party go to their state Supreme Court and ask them to rule that a signature, matching or other wise, not be required for an mail in ballot to be accepted, aside from the obvious answer of course.

Ask another question. If both the U.S. Constitution and the state constitution identify the legislatures of the separate states as the responsible party for establishing election laws what happens if the state executive or the state judiciary put new rules in place that do not comply with the rules the legislature has passed. In other words, they circumvent the will of the duly elected legislature. Why should votes be counted that do not comply with the legally passed election rules??
