More than that, main-in ballots go a long way towards reducing voter disenfranchisement. No need to wait in long lines (way easier if you've got a job that allows that!) or take time off work on a Tuesday.
Honestly, there's no good excuse for all states not following suit.
I remember there was a judge on the ballot, and he had been on the record for some very divisive political takes that I didn't think belonged in our court system. If it had just been me in the voter booth, there would have been a 1/n (cannot remember the number of judges) chance I voted for him at random. And if I can't make a snap decision, I can always think on it for some time. Best way to run a representative democracy IMHO.
How does this have any relationship whatsoever to the way in which the vote is cast?
People can already research to their hearts content without mail-in-voting.
It's easier than also having to find out what is on the ballot, searching, and then remembering each person when you go.
I usually spend a couple hours at home voting and searching before sending the mail in, something that would be a lot harder to do effectively if I had to go in person.
It's a lot easier when you have the ballot in front of you as a reference.
I suspect they either left options blank, voted by party, voted the name they heard somewhere, or voted randomly.
At least for the positions they didn’t know.
It's easier to do it when you can also vote at the same time at home.
