If the Pirate Party started to support cryptocurrencies then the big beneficiary of this will of course be bitcoin. Aurora coin not so much. I do not think they would want to get their reputation smeared for supporting a likely flawed cryptocoin project.
They might support development of blockchain technology but I doubt they will give support for a specific "coin" except for bitcoin which is the most widely accepted and the most proven.
why flawed? Auroracoin is better distributed with the Icelanders then Bitcoin plus it is based on litecoin rather then bitcoin.
Although I would still think bitcoin is a better option for them as it is a bit more stable right now
