Today Bush has the lowest percentage by far and away. The comparison is made by not taking into account anything other than lower court appointments. One must consider the likes of Ginsberg who was approved without hesitation by the conservatives. Statements such as it's common to have these people held back are inane. check Ruth's background before she was voted on and tell me she isn't as far left as one could possible imagine.
As I recall, didn't Clinton name a couple of other people before Ginsberg, but they backed out early?
