Long-distance voting

I sent in my absentee ballot for the US election this morning, doing my small part. Not that it will make any difference. I've linked to pollster because they have state-by-state pages, which cannot be said of the otherwise superior fivethirtyeight, which currently projects WA to Obama by 14.6. Not exactly a squeaker. Speaking of your vote mattering though, those same clever guys at 538 have an interesting analysis of how likely it is that your vote will matter. Tragically, for some of the most strongly-opinionated people I know, that chance is identically zero, as many of those most interested in the outcome aren't US citizens at all...
