ADDED: Here's how the Milwaukee Journal Sentinel talks about the event:
The day after Barack Obama's Wednesday night debate with Mitt Romney, he'll seek to show an image of strength by leading a rally on the university campus here - long a bastion of his support.Here's the University of Wisconsin's own "Guidance on Political Campaign Activities at University of Wisconsin System Institutions."
The event will give the president a chance to either sustain any momentum he has coming out of the debate in Denver or to change the subject if Romney, the former Massachusetts governor, scores points in the forum.
ALSO: Back in August:
The University of Virginia has declined a request to host President Obama for a campaign rally next week, complicating his planned tour of swing-state college campuses to court younger voters...Of course, needing to offer Mitt Romney the same accommodations is not an issue here at the University of Wisconsin—Madison, because it's such a strongly left-liberal environment that he'd never ask.
“The use of either of the desired sites would require closing buildings adjacent to the sites for the entire day,” [university spokesman Carol Wood said]. “The cancellation of 186 classes would occur. … This would result in an extraordinary disruption of the second day of the new semester.”
Wood said the university would also have had to foot the bill for added security measures on campus and along the presidential motorcade route. Because of the school’s nonpartisan status, it would have to offer “the same accommodations and bear the same costs” for Mitt Romney, she said.
UPDATE: The University itself is now openly calling it a "campaign rally": "President Barack Obama will hold a campaign rally on Bascom Hill this Thursday."
