that allowed "no excuse absentee" (mail-in) voting, the stipulation being that if we wanted to "vote by mail", then around the beginning of each calendar year, we would need to request to do that. And if an optional box was also checked off on that no-excuse absentee ballot application, then voting that way would automatically be applicable for any other election for that year (including special elections and the general election), and mail ballots would also automatically be sent out for those subsequent elections that particular year.
They dubbed the list of those interested in this type of voting as "permanent", but in reality, it only means that it is a "mailing list" and each year, the county will send out a notification to voters on the list that invites them to "apply" for such a ballot, and will do so each year. And if that application is not completed, then no ballot will be sent that year and the person would need to vote "in person".

And in the case if someone decided to go on and vote "in person" after having received a mail-in ballot, then they need to bring it with them to the polling place and have it "spoiled" (removed from the system as valid and destroyed).
In this specific case, IMHO, it behooves that we get people into the habit OF voting. There are far too many (particularly Democrats in urban areas) who feel they only need to either vote once every 4 years or maybe twice in a 4 year period (particularly if there is a gubernatorial or mayoral, etc., election that might garner a little more interest).
Every single year, there is some election. EVERY YEAR. We continually get fucked at the state & county levels because of this lack of turnout and interest in down-ballot races that happen in "boring off-year elections".
