Depends on which problem you are referring to; the onerous, humiliating and disgraceful confirmation process that the SC nominees are subjected to, or the problem of the President nominating an unknown entity devoid of any judicial record with which to identify or deduce her positions on the most important, (and most divisive), issues of our times.
During the campaign President Bush stated that he would appoint SC Justices "in the mold of Clarence Thomas and Antonin Scalia", which he did with Judge Roberts. But in no way can anybody compare Harriet Miers to either Scalia or Thomas because she was never a judge and there is not much else to compare. There is, however, a record hinting that Miers was a feminist and had some liberal leanings. Personally, I wonder what was going through her mind during the Clarence Thomas confirmation hearings, when the feminists tried to torpedo his nomination with wild accusations of "sexist" escapades. We'll never know.
Unfortunately, when the President appointed Roberts to replace Rhenquist, conservatives probably didn't gain much ground and may have even lost some. (Rhenquist was viewed as a staunch conservative while many people view Roberts as a 'moderate conservative'). Since Roberts stated that he won't be bringing his (Catholic) faith to work with him, that his beliefs will "play no role" in his decisions, I too wonder about how conservative he is. Meanwhile, the bothersome question remains, "Who is Harriet Miers, and will she be a steadfast conservative or just another moderate like Sandra Day O'Connor"? If Miers proves to be a moderate then SCOTUS may look more liberal than it did before Rhenquist died and O'Connor retired, and we will have gained nothing.
So far, apart from rumors and gossip, the only reassurance we have is, "don't worry, she's a Christian and you'll like her". I just think conservatives deserve a little more assurance than that.
Hey, look, we don't disagree at all. I do think we deserve more than that just as I think we deserve more than the out of the box attack on her education, the irrelevance of her experience and accusations of mediocrity before the woman has even spoken at any length.
