Laws that automatically register residents to vote in elections a. have been enacted by only five states. b. have been enacted by exactly half of states. c. have been enacted by all 50 states. d. are explicitly prohibited by the Constitution.

Answer: The answer is not among the options.

Only 16 states and District of Columbia have enacted the law (which is above half of the state).

Explanation: Voter registration (or enrollment) is the requirement that a person otherwise eligible to vote register (or enrol) on an electoral roll before they will be entitled or permitted to vote. When the registration is automatic, it means you can use any means of government-approved id for voting. Automatic Voters Registration makes voter registration "opt-out" instead of "opt-in"; eligible citizens who interact with government agencies are registered to vote or have their existing registration information updated unless they affirmatively decline. These are states that have enacted the law; Alaska, California, Colorado, Connecticut, District of Columbia, Illinois, Maine, Maryland, Massachusetts, New Jersey, New Mexico, Nevada, Oregon, Rhode Island, Vermont, Washington, West Virginia.

You must establish your voting residency address at least 30 days before Election Day.
