Election Day is rapidly approaching. Are you registered to vote? Do you know where to vote? What time do the polls close?

The 2016 campaign is one of the closest races in modern-day presidential history. How will that affect voter turnout, especially among young voters? Millennials make up about a third of the electorate and have the lowest voter turnout of any age group, according to the Pew Research Center. Less than half of registered voters age 18-35 voted in the last presidential election.

Here's what you need to know to make sure you can cast your ballot on Nov. 8.

There's still time to register to vote.

The rules for registering to vote vary among state to state. Some states require you to register at least 15 to 30 days before the election. Others allow in-person registration if you meet certain requirements. North Dakota is the only state that doesn't require you to register to vote but does require identification at the polling site.

Several states allow online registration, including California, Delaware, Maryland, Minnesota, Missouri, Oregon, Pennsylvania and Virginia. And websites like RocktheVote.com are reaching out to young voters to get them to the polls.
