Nope. As CustardMite said, it has nothing to do with it. Quality score and CTR (And a few other SMALLER factors) effect your bid.

I've heard that it does have a small effect on the landing page part of the algorithm. But it is more of the trust rank rather than page rank. i wrote a post today on my blog about dealing with quality score . I also heard some new info that may help you get lower min bids.
That is incorrect. Have a read of Brads article here: http://www.ewhisper.net/blog/google-adwords-quality-score-factors-demystified/
Nope. I've just participated in thousands and thousands of tests which have demonstrated time and time again the PR has no impact on your QS. In your blog post you said; "They (Google) will obviously also assign a lower minimum bid to a non-commercial site because of probability of less funding." And the evidence to the support that is...?
That's an excellent article btw.. so are you saying google doesn't evaluate the domain at all? i was talking with jon from wikedfire last nite and he said they do if you read my first post in this thread i said "trust rank rather that page rank" but your right, page rank itself has had no bearing on the minimum bids for me either, but placing on diff. domains has showed a change (however very small) in the past. as for my post in the blog, i should have written in my opinion. i put an edit for the blog, thanks for catching that
