Don't matter what you or we are "fine" with.
Bush's goal is to nominate the rightward most nominee who is confirmable. This may be that person. In his opinion, it is.
Yeah, he really pushed the bounds. He picked someone who looks like the crypt creepers older, unmarried sister. She's 60 and not exactly a youthful 60, maybe if Bush is really lucky, Hillary will have the occassion to name her replacement in the years 2009- 2017.
