"And any postal ballots with no signature will most likely be ruled invalid"
Every State is different !!
Look at the complexity required to vote by mail !
1. Don’t open your envelope until you’re ready to vote. Your absentee ballot will arrive with either one or two envelopes; you must use them to return your ballot. If you use a regular envelope, your vote may be tossed.
2. Read the instructions! Absentee voting involves several steps, and not all of them are obvious.
3. Fill out your ballot slowly and carefully. Most jurisdictions require voters to use a pen when filling out absentee ballots.
4. Figure out if you have a secrecy sleeve, and use it if you do. As I explained above, in many states, absentee voters are provided two envelopes for their ballots: an outer envelope and an inner envelope, also known as a secrecy sleeve.
5. Sign one or both envelopes. Some states require voters to sign both the secrecy sleeve and the outer envelope. Others require just one signature, usually on the outer envelope.
6. Get witness signatures and/or a notarization if necessary. A minority of states require one or two witnesses to sign and date your absentee ballot envelope. Some waive this requirement if the ballot envelope is notarized. A few require envelopes to be notarized.
7. Seal the outer envelope and affix a stamp, if necessary. Many states provide prepaid postage to absentee voters, but, unfortunately, some still force voters to pay for their own stamp.
8. Place your ballot in the mail—or drop it off in person. Regardless of whether your state pays for postage, you should think about dropping off your ballot in person to avoid potential Postal Service delays
9. Track your ballot online or by phone. Whether or not you mail your ballot, you should ensure that it has been received by election officials (ideally well before Nov. 3). Many states now allow voters to track their ballots online. This system will note if a ballot has been “accepted” or “rejected.”
10. Be on the lookout for letters, emails, or phone calls from election officials in the days after the election.
A majority of states now provide a ballot “cure” process that directs election officials to notify voters with faulty ballots and tell them how they can make sure their vote counts. This backstop is especially helpful in states that compare voters’ signatures to confirm their identities. If your ballot is flagged for “signature mismatch,” you may be allowed to prove who you are by other means. "
