Here's a take that I'm ashamed to admit I hadn't considered: Members of Congress may be protecting Bush because of votes they made previously that might seem to have supported his illegal activities
. While it might not end in prosecution, it could end their lucrative Congressional careers.
So, of course key Congressional Democrats who were made aware of these illegal torture and surveillance programs are going to protect the Bush administration and other lawbreakers. If you were Jay Rockfeller or Nancy Pelosi, would you want there to be investigations and prosecutions for torture programs that, to one degree or another, you knew about? If you were Jane Harman, wouldn't you be extremely eager to put a stop to judicial proceedings that were likely to result in a finding that surveillance programs that you knew about, approved of, and helped to conceal were illegal and unconstitutional?
