This is what's worrisome about Dr. Rice. She's too polite and her voice tends to quaver. No experience at campaigning, and the run for the presidency is big league campaigning. Too nice to deliver a punch, or too afraid to offend, Rice could snatch defeat in '08, even against Hillary. Not that I expect it'll be Hillary.
1) Condi has stated she isn't running.
2) I've never seen Condi cower from any fight. You would be the first I've ever seen suggest that. If anything she is at times even more blunt than the President himself. Further this woman is smart, witty, articulate, quick thinking, with the ability to disarm with a smile. She'd rip Hillary to shreads without breaking a sweat. If you doubt the fear Hillary holds towards Condi, review the knives drawn against here during her confirmation and the weeks following. It isn't Condi in fear, it is Hillary Clinton.
