Another Libertarian for Obama?

Will Wilkinson writes

I think it is blazingly obvious that John McCain, as a matter of temperament and values, is completely unfit to be president. Giuliani’s convention speech about how the election is like a job interview only affirmed for me Barack Obama’s superior qualifications. He is a man of remarkable competence, with an eye for both the big picture and the institutional details, who has a sober temper and an evident ability to inspire and effectively lead those reporting to him. He’s just the kind of guy I’d want as an executive, were I filling an executive position. Joe Biden is qualified to be president in much the same way McCain is; he is a lifelong asshole and American senator.
