Today is Election Day and if you haven't registered to vote, you'll still be able to cast a ballot -- depending on where you live.
Voters can still register to vote in 19 states, and the District of Columbia.
States including California, Colorado, Connecticut, Hawaii, Idaho, Illinois, Iowa, Maine, Maryland, Michigan, Minnesota, Montana, Nevada, New Hampshire, Utah, Vermont, Washington, Wisconsin and Wyoming all have same-day registration.
You will likely need to provide proof of identity and residency to register. If you cannot provide one, many states will allow you to cast a "provisional ballot," which will be counted once the right to vote has been verified.
Only one state does not require registration to vote. In North Dakota, voters just have to show up to the polling station with acceptable identification, which shows a residential address and date of birth, to cast a ballot.
Most states do not require you to bring your voter registration card to the polls. But a majority of states do expect you to provide another form of ID to vote in person.
Even if you do not have a form of ID that your state asks for, you may be able to vote. Some states require you to take extra measures after you vote to make sure that your vote counts.
To see state-specific information, including where to register and what documents are required, go to vote.gov.
Not sure if you're registered? You can visit vote.gov to check your status. The website also provides links to state election websites so you can see your polling station location and look over a sample ballot and voter's guide.
You are allowed to bring your notes, a voter's guide or a sample ballot into the voting booth. This frees you from having to memorize your choices for candidates and ballot initiatives. Some polling places do restrict cell phone use, so bringing paper copies instead of using your phone is encouraged.
