This didn’t happen because of John G. Roberts, William Rehnquist would have made the same decision.
This happened because of Samuel Alito taking over Sandra Day O’Connor’s spot and because of conservatives who stood up and fought for a conservative pick when Bush picked Miers and stood up and fought for Alito when Bush gave us that conservative pick. A great day.
I believe you're right. It wasn't just the fact that Miers was unqualified to be a Justice of the Supreme Court, but it was her lack of demonstrated positions, rulings and interpretations on important issues. I did not feel confident that she was pro-life. I'm glad we fought the good fight and got Alito in there instead of Miers. He is a much more solid Justice than she ever would have been.
