Oprah was extremely effective in directly attacking the idea that Hillary is more experienced and seasoned than Obama. She did a great job of positioning Obama as the candidate of change vs. Hillary. Hillary's response with radio ads from Maya to my mind betrays her weak point: she is the establishment candidate. For an electorate interested in change, she is not the candidate. Many of her endorsements reflect her establishment status (Andrew Young, Maya Anjelou, Quincy Jones etc.). The Obama campaign is getting better at painting her in this way. So this weekend is a major victory in the election war.
Hillary's response with the Maya Angelou ads can certainly be considered only part of her response. She has a highly organized campaign and organization wins elections. She's smart and she's ruthless and not without weapons of her own, such as Bill and plenty of money too.
Obama is picking up the big mo. He's challenging her in Iowa, competing in New Hampshire and may perhaps have generated momentum in SC. He's fighting an intense three state war for the early primary states and as the primaries get closer, the gloves are coming off. Lets get ready to ruuummmbbblleee!
