New Hampshire ranked second for state participation at 45 percent. Conducting elections by mail is much easier on the election administrators. Particularly in local elections, primaries, and local ballot questions, mail-in elections make sense as a place to start and to experiment. Mail balloting in such local elections has also resulted in increased turnout. There is more room for corruption when election administration officials have to basically conduct two parallel systems.
Voter lists are much easier to accurately maintain with mail balloting.
This is because ballots that are returned to election officials as undeliverable highlight registrations that must be checked. This helps election officials purge their registration rolls of ineligible voters. A more informed voting public is cited as another advantage of mail-in balloting. If an individual has two weeks between when he or she receives a ballot and when it must be returned, this allows a better opportunity for voters to study the issues, to clarify any points of confusion, and get questions answered. During this 1995 election, Oregon became the nation's first state to exclusively use mail balloting to fill a federal office.
