Will running Adsense lower my Quality Score

[beedub]

Does anyone have any evidence...or an educated hunch :)...that running an adsense block on an adwords landing page will lower the quality score?

My educated hunch would be "no", although I did observe a year or two ago that having adsense on your site the first time it is organically crawled was a bad idea.

The people who are getting in trouble for adsense arbitrage are having their adsense accounts terminated, not their adwords accounts.

Actually, I think this past summer some AdWords advertisers were told that their business profiles weren't a good match, or words to that effect, and asked to leave.

However, I can state unequivocally that I run AdSense a bunch of personal sites, and I use AdWords to drive traffic to my most prominent site, and the quality scores on 928 out of 930 keywords have been 'great' for over six months now.

Thanks for the input!
