Donate to Candidates Through Search

We had a story appear on the Digg homepage the other day and in the comments someone pointed to a site I hadn't seen before: Presidential Quest.  

Basically Presidential Quest has created search sites for every single Presidential candidate.  Users then search the web from the site of their chosen candidate and all the ad revenue that is generated from the searching is donated to their chosen candidate.  Here is a link to Rudy Guiliani's website as an example.  

They have another site that donates search revenue to charity. 

This is a good example of what Jason Calacanis calls media philanthropy and I think it is a great idea.  The rub is that for this to work the actual search engines on these sites will need to be in the same ballpark of the industry leaders in terms of quality.   I haven't look at it enough to judge the search quality yet.
