“Anyone who is capable of getting themselves made President should on no account be allowed to do the job.” // Douglas Adams

I gather it is a bigger thing to go for a third party in the US than in the typical multi-party systems present in Europe. However, just maybe you could find something in the “Pirate party” movement. (Started in Sweden; some useful links: http://en.wikipedia.org/wiki/Pirate_Party , http://www.piratpartiet.se/international/ , and in the US: http://pirate-party.us/ )

Note: I’m not saying hackers are automatically pirates and all of them support the the core politics of this movement (privacy, rebalance of copyright and patents) but I suspect the ‘density of hackers’ prepared to engage in politics is higher there than in other political movements/parties.
