Bring back Patrick Fitzgerald?
This is a significant scandal that is large and getting larger. It will collide with Hillary Clinton's (D.-MoveOn.org) campaign again and again, and each time there will be the patented Clinton stonewalling combined with cries of political prosecution. The Clinton machine will gear up and assault any prosecutor just as it did Dean Starr.
So acting Attorney General Peter Keisler should get ahead of the ball and call Patrick Fitzgerald out of special prosecutor retirement and turn him loose on Norman Hsu. Fitzgerald's got a lot of experience with corruption cases in Illinois and of course he's got credibility with the fever swamp. If the radical Hillary becomes president, that'll be the end of DOJ investigations into her campaign finance carnival, but not if the investigations are already grouped under one high profile prosecutor.
