As few restrictions on the right to vote as there are, the comparison is inapt. What you may be missing is that there are plenty of constraints on the act of voting, as well as the process. You can't pay for votes, you can't have someone sign their vote-by-mail ballot and fill it in for them, you can't vote in-person in someone else's stead (even though it doesn't create an extra vote), and so on. There are also plenty of restrictions (at least in the text of the law) on how to handle the ballots themselves. None of these are restrictions on the right to vote.
