I have two thoughts about this:
- I have no idea why mailing back absentee ballots requires postage. This is something that I believe out taxes should pay for and it shouldn't cost much because the infrastructure is already in place. you're paying for the trucks gas and personnel if the ballots are being mailed or not. The change in cost is incremental.
- Who the heck doesn't know how to buy a stamp? In kindergarten my class wrote letters (may it was a card) to our parents, addressed the envelope, walked to the post office, bought a stamp and mailed it. IN KINDERGARTEN.
