Bring Back Bork
After mounting criticism from conservatives, Harriet Miers decided to withdraw from the consideration for a position on the Supreme Court. Misgivings about her competence for this very important position had not been assuaged as people got to know her better. This made an already uphill battle that much harder. Faced with these insurmountable challenges, she probably decided that it did not serve either the President or the conservatives in general to remain a candidate. Ironically, this may be the best proof of her conservative credentials.
So now the guessing game about the next Supreme Court nominee starts anew. Some of the most prominent contenders are judges Michael Luttig and Samuel Alito (story). From what I have read about their backgrounds, either one of them would make a supreme candidate.
