In the past two years, thirteen states have tightened voting laws.
Some states have restricted early voting, made it tougher to restore voting rights for ex-cons, or required some form of identification.
But California has recently enacted online voter registration.
And this year a law was passed to allow same-day registration beginning next year.
But Jennie Bowser with the National Conference of State Legislatures, says California isn't unique in making it easier to vote.
BOWSER: "I think there are a lot of things that legislatures are doing and election officials at the state and local level are doing every day to try and make elections more efficient and more fair and to maximize opportunities to vote that aren't attracting the attention that really some of these really big high profile changes are attracting."
Bowser says in the last ten years, there's been a large expansion of early and "no-excuse" absentee voting.
And 11 other states offer online registration.
