I think you mistake the reason of opposition to Miers.
The objections largely fall under:
- Not having the qualifications of some of her competitors
- prefering a candidate that is not stealth
No responsible critic has leveled the charge she is a Liberal. They instead state they do not know.
So, no, withdrawal of the objections will not be forthcoming because these objections are constant no matter how she behaves on the court.
Thank goodness, someone else gets it!
