Well, a lot of ways. You do it at the post office rather than at a polling place - this may be a critical difference for populations routinely underserved by few polling places with long lines. You can also submit a ballot that you carefully filled out at home with all your research materials next to you.
It’s pretty obviously different. But I think what you are really saying is “I don’t want to have to go anywhere further than my own mailbox to vote.” And I’ll grant you it is less convenient than that. I know convenience always makes a difference, and for some people is actually more like accessibility. But if voting takes a little effort… just do it. I always drop mine off at my polling place rather than mail it. I like the ritual.
