According to Torrentfreak, the US Pirate Party is endorsing Barack Obama:
The Pirate Party just published a press release in which they show their support for Obama, and ask their members to support him as well. Obama is indeed the only candidate who’s even been willing to consider copyright change, the others are more interested in protecting the commercial rights of a few. Other than that, he has a healthy view on how to ensure people’s privacy and he values net neutrality.
Andrew Norton, a spokesperson of the US Pirate Party told TorrentFreak: “We believe in democracy, and progress. Since we are not putting forward a candidate of our own, we stand solidly behind Mr. Obama, as he is the only candidate that seems to realize that personal privacy is a right, not a privilege, and believes that copyright is, as the constitution defines, for progress, rather than profit.”
