Worse than Nixon?

Anonymous Liberal has a nice wrap-up of the relative strength of the NSA's wiretapping program as compared with Nixon's wiretapping efforts. The conclusion: Nixon had a better case than Bush, and still lost. All the arguments for executive authority were basically demolished when Congress instituted the FISA court to oversee domestic wiretapping warrants. I suspect that any movement for Bush will come either from the Republican's political hegemony or from a peculiar judicial blindness to the 'unified executive' doctrine, which my last post discusses.
