Is there a non partisan website that acts as a clearinghouse for accurate, up to the minute information concerning political campaigns?

If so, what is it?
If not, why doesn’t this exist?
Is it too large a task, or is there simply no will to create it?
If there is no will to create it, why not?

I am thinking of a place voters could go to find out the real statistics, facts and history concerning issues and accusations made during political campaigns. I am thinking of a place (somewhere over the rainbow) where the spin doctors cannot keep a toehold.

If a candidate twisted the facts or gave inaccurate statistics he/she would get corrected. If a voter was looking for facts relating to a speech or debate they had seen aired, there would be a searchable way to get the facts.

I know that the news is supposed to serve this function, but even if it were unbiased, which it often is not, it cannot get into the detail of things said and so, often, I feel like candidates are getting away with many inaccuracies and purposely twisting the facts. Shouldn’t there be a way to call them on it?

If you think it’s possible, how would you monitor the site in order to maintain accuracy?
Would it be a good idea to post retractions when information was wrong or inaccurate?
Any ideas?
