The Atlantic Monthly (also just called The Atlantic) is a monthly magazine based out of Washington, DC. First established in the mid 19th century, the periodical publishes articles on politics, reviews books, and publishes fiction and poetry.

In the September 2008 issue, The Atlantic Monthly published documents detailing communications within the Hillary Clinton Presidential campaign about how they should go about defeating Democratic rival Barack Obama in the primary elections. The documents appeared to show how disagreements within her staff may have led to Clinton's eventual loss to Obama.
