There are no excuses for not voting (if you're dead, see the previous paragraph). Except if you're in North Carolina: Neither of your senatorial candidates seems to understand that the public display of conservative protestant christianity is not a qualification for office. And it's not much better in Mississippi.
Just vote. And if you are related to a veteran, or active-duty soldier, sailor, or airman, remember that the reason they fight is tomorrow... the real Veterans' Day.
