He did end up getting a good amount of attention in 2004...but that may be more because he was the "anti-Kerry/Dean". Maybe that's also a bit where Obama's popularity comes from: he's not Hillary.
Neither is Senator Joe Biden or Governor Bill Richardson. Two democrats I could actually stand as President and two who can appear more moderate and win. They are not Hillary and have tons of experience in foreign policy which dems need to win in 2008. Why not them? Why a guy who has been Senator for less time than I've hosted "The Tropical Roundtable"?
