I heard her say it on Sean's radio show this afternoon, too. It didn't sound "tongue in cheek" to me. It actually made absolutely no sense. Everything about Bush indicates he takes his job seriously and if he chooses a Supreme Court Justice out of a motivation to spite a certain group of conservatives, then he's not even 1% of the man he portrays himself to be in almost every other way. He knows the importance of this particular appointment to the SCOTUS and I believe he's chosen accordingly and it will become evident in the days ahead.
I didn't hear her on the radio. I just saw her on TV. She had a smile on her face and Sean laughed a little too.
I thought it was funny. Not true, but funny.
