Kenny,
TexasBlueBell found this link for me which gives an account of the only link which appears to create a causus belli for the Chicago move from Havard Law Review (not exactly a step up, ya know? No ‘bright’ person with hundreds of thou in debt decides to avoid all the recruiters to hang around Harvard and head to the slums of Chicago as a total stranger).

The plot thickens. The "law firm" is the Ayers family firm, where Ms. Dohrn worked and was the mentor of Michelle. This is the source of the funding Weatherman Terrorists Ayers and Dohrn received from Ayers' father during their years on the run.
Bill Ayers is very close to ACORN (a Director then, as BHO became).) The UK article does not mention the ACORN connection and does not even hint at the Chicago Public Schools Project, which Obama and Ayers turned into an unmitigated disaster.
This article is more like an adulatory press release than news. It is understandable, if not obvious that Obama's terrorist connection wired him as the community organizer, got him into Harvard, and put him up for office.
The Daley Machine was either too dumb to fathom the commie connection, or too cynical to care.
