Gov. Scott Walker?s proposal to break off the Madison campus from the rest of the University of Wisconsin System is dead. UW-Madison Chancellor Biddy Martin said Friday it?s now clear there?s not enough support for the UW-Madison split at this point, though she?s optimistic a similar plan could be studied. “I don?t think anything is foreclosed,” Martin said. “I think there?s a huge amount of interest that?s been demonstrated in change, I just don?t know what the ultimate outcomes of these various efforts at change will be.”
