Yup--good thing that's not what AC said. Your argument that a justice doesn't need anything other than a bit of common sense is at least as silly, though. "Common sense" is a far cry from enough.
We're told she has terrific "common sense." Common sense is the last thing you want in a judge!
Ann said that common sense was the LAST THING we wanted in a judge. And she didn't mean it was the last of a list of things she wanted, she meant it was something you definitely did NOT want.
I did use logic to determine that if you did NOT want a judge with common sense, then you must WANT a judge with no common sense.
I'll readily admit that I don't believe Ann MEANS this, but she certainly did SAY it, and she meant to say it -- this isn't her being sarcastic.
