I'm in a similar spot - overseas at the moment, voting district in Erie (also a crucial county), ordered the ballot in early October and just got it last week, which was obviously too late for it to get from Iceland back to the elections office in Erie in time. As far as I know, there's nothing you can do about it except grumble. Maybe find a friend who wasn't planning on voting and get them to vote as a favor to you. That's all I can think of.
