The issue is whether or not President Bush was even willing to fight for her-or anyone with a discernible conservative viewpoint and a distinguished scholarly and/or judicial record-and stand behind his decision.
I'm almost certain that Ronald Reagan believed Judge Bork was going to be confirmed before he sent his name to the U.S. Senate, but the fact that his nomination was eventually rejected does not retroactively make his initial instincts incorrect.
I think the potential success of a nominee is also a consideration, in addition to the point you raise.
After nominating two stealth candidates, it does appear questionable as to whether President Bush is willing to fight for candidates with a discernible conservative viewpoint, I agree.
But Rogers-Brown would have been a good choice both because she was an obvious conservative with a paper trail and because she would have been confirmed.
The Reagan whitehouse was caught totally off-guard with Bork, and did not put up a good defense. It is most unfortunate. He would have made a superb justice and was an excellent pick.
