yep same thing here.. I actually returned mine yesterday. I'm registered for a permanent mail ballot for every election and they always notify me when it hits the mail, then notify me when they have received it back from me.
It's really quite easy and I think all states should do it.
Of course there could be some drawbacks in rural areas, especially the ones that have experienced disasters like the recent storms have presented. There should be a way to get everyone to the polls and the mail seems to be the safest with signature verifications and feedback from your state if they find something is not right.
I don't think we can go full internet because as we have seen with hackers and things, it could be manipulated. The overseas residents present a whole different aspect, including our military members so there should be a place for all them to vote and be verified.
