Context: Unlike what neo-liberals say, market and democracy clash at a fundamental level. Democracy runs on the principle of 'one man (one person), one vote'.

I'll actually go ahead and agree with you on that one." - YouTube video including the statement in Columbus, Ohio (28 October 2008) http://www.youtube.com/watch?v=71iNvPQXuk0
