Fascinating article here about the Obama phemomena, from someone who was "on the ground in Iowa.
http://www.zmag.org/content/showarticle.cfm?SectionID=90&ItemID=14670 I haven't digested it all yet but he gives a handy explanation that explains this "revolution" - corporate money and vague generalisations ("hope", "change", "freedom")employed frequently enough to create the illusion that he's some kind of left leaning progressive. Interesting stuff.
