If you want to vote, check the rules beforehand.
If you live away from your parents’ place to attend college, you may choose to vote either at your college location or absentee at your parents’ place. In either case, you need to check the rules to make sure that you are not disenfranchised (e.g. by not having one of the specified kinds of photo ID in some states).
