ADDED: From the same article:
Before the president took the stage, Madison congressional candidate Mark Pocan, Mayor Paul Soglin, outgoing U.S. Sen. Herb Kohl, D-Wis., and U.S. Senate candidate Tammy Baldwin set the tone for the afternoon, encouraging attendees to get out and vote.So there was no pretense at all that this event had anything to do with educating young minds, exploring political ideas. It was unabashedly a get-out-the-vote effort... right down to demanding that the students acquire tickets by going to the campaign website and providing their email addresses and phone numbers (which, from what I've heard, were immediately used to spam the students with pleas for donations).
While at the beginning of his speech Obama took shots at Romney, he mostly stuck to talking about his vision for the country and urged the crowd of young supporters to vote in November.
College aged voters showed up at the polls in historic numbers four years ago to propel Obama into office, and Thursday he again pushed for their support.
