Credibility of political candidates

I forgot to post this earlier in the semester, but here's a blog with a really long analysis of Barack Obama's credibility.

The journalists who run the blog are up-front about their agenda, which I think is important.

Personally, I doubt there are more than a handful (if that) of high-level politicians whose credibility couldn't thusly be questioned. But I thought this site was interesting for its approach.

I wonder how many people actually looked at it and/or were convinced.
