I fiddled around with Wolverine Access too, but to no avail.
Finally, I emailed the political science department, and received this in response (very quickly, I might add).
"The admissions committee has made their decisions. However, you will not be receiving and offer of admission. Due to budget constraints, we were not able to make as many offers as would have liked too. Thank you for your interest and applying to the Political Science Program. Best of luck to you, in your future endeavors."
So, I would say that Michigan appears to be done.
I am kind of bummed-0 for 3 so far (Duke, Yale, Michigan) with no word from WUSTL (a faint hope I know) and Iowa yet to come next week, maybe.
