Hillary Clinton has also decided to seek the presidency (I buried the story on Digg, myself) Like that's a surprise. We've all been told she was going to run since the day her husband left the White House.
Personally, I think she's a shoe-in to win the Democrat nomination, even though she's not a Democrat (she's a socialist, her attempt to socialize medicine during her husband's tenure proves this) or even much of a woman, a parent, or a wife. She's connected to Bill, and Bill still pulls a lot of strings in the Democrat party. That's really all she needs to win at this point.
I'm just waiting to see who the Republicans field against her. I'm still betting on Condi; not because she's got a chance of winning, but because polling has revealed that her group (black, female) is the only group less likely to win the presidency than a white female.
...and the Republicans are playing to loose this time around.
Whatever happens in the four to eight years following Bush's time in office, it isn't going to be good. The Republicans want to be able to capitalize on that by blaming it on the next occupant of the White House.
Look to see them attempt to scuttle any other viable candidates (including Dr. Paul, the only Republican that I would vote for) in the coming years, leaving only Condi to run against Hillary.
