I've just been surprised to learn that P-Lib (Partido de la Libertad Individual), a very small Spanish political party, is now accepting Bitcoin donations. They have posted a message on the Bitcoin España Facebook group this afternoon and their announcement with a donation address is here:
http://www.p-lib.es/economia/el-p-lib-ya-admite-bitcoins/ I don't know much about P-Lib and I'm not affiliated with them in any way. They are a very small liberal/libertarian party without any parliamentary representation, not even at the regional or town hall level as far as I know. But the little I've read about them and their political program seems quite interesting. And badly needed in a country like Spain, where most of the political parties adopt a paternalistic view of society where the state is supposed to always be there to pay for anything.
