Of course! But the point of counting ballots after election day is to cheat. They need to see how many votes they need.
Of course thats all it is. The fact of the matter is most peope using mail in voting (legitimate mail in) are probably sending their ballots WELL enough in advance to ensure they are counted.
But the argument these corrupt slobs always use is "well we can't ban ballots AFTER election day because that's voter suppression and all votes wont be counted" And thats why I insist to those people that if they are too stupid to not send them early enough then they are too stupid to vote in the first place.
I bet the VAST majority of ballots counted AFTER election day are fraudulent votes. Probably at least 90%
Which is the argument for why it shouldn't be allowed to happen.
