MADISON, Wis. (AP) – Three University of Wisconsin-Madison professors say students shouldn’t have to register with the Obama presidential campaign to attend Thursday’s rally.  Students are required to supply their phone number and email address to the Obama campaign and click “I’m In” in order to get a free ticket to the president’s appearance at Bascom Hill.  Political science professors Donald Downs and Ken Mayer and law professor Ann Althouse sent a letter expressing their concerns to university administrators Wednesday.   Vice Chancellor Vince Sweeney says the university was simply trying to provide as much information as possible about the rally by putting the Obama campaign link on the university’s website. Sweeney tells the State Journal (http://tinyurl.com/9r2a2zy ) the school doesn’t manage the Obama link and doesn’t collect the information from it.
