When President Obama waded into a gathering of Republican members of Congress on live TV the other day, both sides tossed barbs and scored points. Everyone agreed it was good political theater. But maybe it was more than that. There was genuinely informed debate as both sides made a good-faith effort to explain their points of view. The encounter evoked "question time," the raucous but enlightening British tradition of the prime minister submitting to a grilling by Parliament. A lot of people from pundits to politicians said, "We ought to do that again." Should we? Do you think there's value in the president facing his political opponents—and, perhaps, members of his own party? How would you do it? Drop me a line at email@example.com to share your thoughts.
