On the Democratic side, Obama - by winning in a totally white state - shows that racism is gone as a factor in American politics. On the Republican side, Huckabee's win shows how a truly compassionate conservative can win by harvesting voters who want the message of concern for the poor and for values to prevail.
But what of Hillary Clinton? She's down but not out. In the first really contested election of her own political career, she lost dismally - outclassed, outdrawn and outpolled by Obama.
Her campaign professionals (including Bill) decided to stress experience, precisely the wrong message in a Democratic primary. Prematurely appealing to the center and abandoning the left, she fell between two chairs - not sufficiently centrist to win independents or liberal enough to attract Democrats.
On the GOP side, Huckabee brought a new phenomenon into politics. A New Testament Christian politician, he takes the Biblical message to the center-left, clothing the naked and feeding the hungry. His refusal to indulge in negative advertising sent a message to Iowa voters showing his strength under fire.
...don't write off Obama or Huckabee. Their appeals are truly unique and obviously resonate with voters. Their approaches are now and the outcome shows how relevant their message is.
So does this mean Hillary is going to start swinging left? That seems like it would be the politically shrewd thing for her to do. This certainly looks like it will be an interesting election season.
