With less than two months until Election Day, Tuesday marked National Voter Registration Day, as part of a big push to get voters ready to cast their ballots on Nov. 5.

Registering to vote is pretty easy and painless, especially in states that allow eligible voters to do it online. Unfortunately, Arkansas, Mississippi, Montana, New Hampshire, South Dakota, Wyoming, and Texas do not allow people to register through the web. Voters in those seven states are required to register either by mail or in person.
