If, based on their zip code, voters could access wiki based information about upcoming local and federal races and referenda items relevant to their districts, working families would have a powerful and democratic information resource at their disposal in the ballot box.

I've discussed this idea with Decius in depth. A Wiki voter guide would be possible, but extremely hard. In terms of spam and attacks, this would pose the greatest challenge to the Wiki format either of us can think of. No content would be as charged as a voter guide.

Even seeding the Wiki would be tough. Just finding out who is running in what district and what zip codes cover a district is non-trivial.
