Much has been said about her and why Bush selected her. While I cannot read the mind of Bush, I will make a prediction. Should it come true, I will change the audience of this article. If not, I guess I will delete it.
I think the reason that he picked Meirs is because the right, not the left, was telling him to stay away from Alberto Gonzales. While I dont think he is actually planning on Meirs failing, I thin there is a good chance she will, especially in light of the opposition on the right (and he can count on enough democrats to oppose her). Once she fails, he will then nominate Gonzales as his real choice and the conservatives will not oppose him (grumbling so). Most of the democrats will, but they do not have the votes to stop him.
If I am right, it will truly be a masterful stroke! If not, I guess I just read too much into Bush.
