All I can do is hope that he will. I think Frist is guided by the NEWS of the day, rather than what needs to get done.
My previous point was to challenge your, "Frist ... has pushed GWB's judges through."
I think he, as with most Senators, take a collegial path, looking for least resistance, and all too willing to "give" on something that isn't "theirs" to begin with. That is, I see the nominations as the President's, and Frist doesn't have his heart in them to the point of "fight."
