At today's White House press briefing, David Corn asked Bill Burton whether Obama would commit to holding regular Q&A sessions with Republicans, following the riveting exchange last week at the GOP's issues retreat. Burton basically said no, arguing that the first session worked because of its "spontaneity." This is a pretty weak excuse. If you've ever checked out the British parliament's question time sessions, in which rowdy MPs grill the prime minister at length about the issues of the day, you'll see that they've managed to retain plenty of spontaneity over the years (sometimes a little too much.) In any case, the White House evidently still needs some convincing. Here's how you can help.
