Over the last few years, state legislatures have seen a significant increase in proposals to change how states vote. Quite apart from voter eligibility, or the period during which they can vote, these proposals have suggested fundamental changes in how the ballot looks.
Maine and Alaska are using rank-choice voting in their statewide and federal elections. According to a Congressional Research Service study late last year, more than 50 smaller jurisdictions (primarily cities) are authorized by state statutes to use that method and are doing so. With rank-choice voting, every voter sees all candidates and ranks them according to preference.
