Tuesday is Election Day. You might still have questions. When can you vote? What do you need to vote? Can you cast your ballot if you still haven't registered yet?

CBS News has answers for voters in all 50 states, plus Washington, D.C.

To make sure you get to the polls and have your vote counted — no excuses! — here's our guide to everything you need to know in your state. Keep in mind that regardless of when polls close, state laws require that everyone waiting in line can still vote. Most states also have laws requiring employers to let you take time off to vote, which we've noted here as well.
