Rove had a political plan for a permanent Republican majority.  One of the pillars of that plan was to gain control of local governments, where elections are run, where news is disseminated, where political rewards are distributed to patrons.

During the Bush Administration, Rove's office engaged the Justice Department to target hundreds of local politicians (Democrats and a handful of liberal Republicans) that got in their way.  Justice would assign investigators to find dirt on each target, then coerce friends and family members into testifying against them using more political prosecutions.

Cases were assigned to prosecutors who had a political interest, and the system for random assignment of judges was (illegally) bypassed to channel them to newly-appointed Bush judges.

We've heard of Don Siegelman because he was a Governor, so his case  commanded a small amount of mainstream press. But the "iceberg" of which he was the tip is now coming to light.
