Moreover, she either honestly believes that W is, in fact, a real smart feller (which is hardly a "mainstream" opinion) or, she regarded it as prudent "strategery" to "disassemble" on the record with such a blatantly outlandish (and, frankly, insultingly fatuous) assertion to this effect. 

Is this manner of judgement suitable for a Supreme Court justice?

It's ironic (in a tragic/nauseating sort of way) that it was "Poppy" Bush who put Clarence "the good negro" Thomas on the bench, and now his hapless namesake is going the same hideously cynical route by selecting a fawning and/or conniving female to fill the current vacancy.

Sadly, Miers' gender--in and of itself--will go a long way to neutralize opposition to her nomination from the left, just as Uncle Clarence's race did for him.
