LOL. Wow. You are so intelligent to use two 3 syllable words in one sentence. I'll bet you impress everyone down at the bar and restaurant.
Ballot deadlines and voting laws are determined by each state's legislature.
What has happened recently is a spate of DEMOCRAT-backed court cases seeking to nullify state election laws by judicial fiat, particularly in battleground states like Wisconsin and Pennsylvania.
But you knew that, didn't you?
Let's look at the PA case.
State law says the ballots should be postmarked by 8PM on election day, Nov 3.
That means state law allows for ballots to arrive after election day and be counted.
Any ballot received on or before election day would meet the law's requirement even if the postmark is not legible. So clearly some ballots without a legible postmark will be counted. To not count a ballot because the postmark is not legible would violate the law and disenfranchise voters. The issue here is ballots that arrive after election day that don't have a legible postmark. In order for the ballot to be illegally sent under the law it would have to be mailed after 8PM on election day.
Mail currently is never delivered the next day after it is mailed. Mail dropped off after 8pm would normally be postmarked the following day. That means any ballot dropped off late that gets a legible postmark would be rejected under the law and the court ruling. So the court ruling only applies to mail without a valid postmark. Ballots received the day after the election would require that they have been mailed on or before election day to arrive that day. Those ballots would be legally counted as long as the postmark is legible. The certainly would show the voter intended to vote and had sent the ballot in ahead of the deadline. The failure of the Post Office to put a legible postmark on the envelope is not the fault of the voter and yet you would punish the voter for the failings of the Post Office.
The real issue here is how many envelopes containing ballots will arrive after election day that don't have legible postmarks. It may be zero. It may be 10% of the ballots received. The most likely scenario is less than 1% will not have a legible postmark. Let's wait and see how many ballots this would actually apply to before we claim this ruling will change any election outcome. Based on the current number of absentee ballots already received in PA compared to the number of ballots requested there may be about a million ballots that haven't yet been returned. If we assume that 1% don't have a legible postmark that would mean there could be 10,000 ballots in question. Less than the margin of victory from 2016. If we assume 10% then it would be 100,000 which is more than the margin of victory.
But all of this assumes that those million remaining ballots are somehow mailed after election day and almost all of them don't get postmarked and all of them are votes for Biden. We are now in the Twilight Zone for conspiracy theories here. The court made a reasonable assumption that few ballots would be mailed late and a small percentage of those might be missing the postmark. Far more would likely be mailed on election day that are missing the postmark and therefor the voter shouldn't be punished for the failings of the Post Office.
If after the election you can provide evidence that the margin of victory for Biden is less than the number of ballots received after election day then you might have an argument. But without that evidence, you are simply making a fantastical leap of speculation that defies reality.
