Here's some links
The US Pirate Party Wiki (Yes, the wikipedia page is biased, so I chose the wiki)
Ans as for the copyrights, I believe they're talking about whwat it used to be. I think they're okay with copyrights as long as the original artist is alive and they're not being a copyright troll (think patent troll, but with copyrights). It seems that the Digital Millenium Copyright Act is the one they have a bone to pick with.
This section of their wiki is what you'll probably be interested in. Let me know what you think.
And TB would ''love'' to chew this over.
Granted however, every party has it's fruitcakes, and the USPP is no exception
