Rezko's guilty. Who's next?

The Chicago Tribune reports:

The Justice Department's prosecution of Antoin "Tony" Rezko was always about prelude, never about climax. The jury's conviction of Rezko Wednesday on 16 criminal counts is one more point on a long investigative arc—an arc now pointed directly at Gov. Rod Blagojevich and other of his associates.

That arc reaches beyond the horizon to points none of us can see. But prosecutor Christopher Niewoehner unequivocally—and forcefully—told the Rezko jurors during closing arguments where federal authorities now are concentrating: "This is a crime that involves the highest levels of power in Illinois."
