From ABC News’ Political Punch blog:

After a weekend of relatively tame town halls President Obama found one vocal skeptic in a college student who challenged the President to an Oxford debate over the public option at his Grand Junction, Colo., town hall this evening.

Zach Lahn, a 23-year-old student at the University of Colorado got the President’s attention after shouting out during the Q and A a few times. [Pols emphasis] The President finally called on him during the end of the town hall.

“I just want proof here that I’m happy to get a good debate going,” the President said, knowing that he could be wading into harsher waters than he is used to.

“I’d love to have a debate, just all out, anytime, Oxford-style, if you’d like,” Lahn said to President Obama and then proceeded on with his question. “How in the world can a private corporation providing insurance compete with an entity that does not have to worry about making a profit, does not have to pay local property taxes — they do not have to — they’re not subject to local regulations? How can a company compete with that?”

Lahn said he didn’t want any generalities, or philosophical arguments from the President as a response…

“It’s good to see a young person who’s very engaged and confident challenging the President to a Oxford-style debate, I think this is good,” he said. “You know, this is good. You know, I like that. You got to have a little chutzpah, you know.”
