I suspect most americans want a new face at the top.
Hillary, Guiliani, McCain, Biden, Gore and Newt are soooo 90's.
That is why I think Obama is doing well right now on the left. And why Duncan Hunter has a real shot for the right.
You make an interesting point.
I would add that most will end up wanting a known commodity.
Who can carry the nation and lead - and who has shown it to-date.
And I suspect you didn't read the article.
Obama got less then HALF of Missus Clinton's support, and Duncan Hunter was a non-entity.
