Obama is adressing the GOP retreat in Baltimore right now, and it's being televised live. It's remarkable that Republicans agreed to this. The guy at the mike always has an advantage in these kinds of forums, and in any case Obama is better than most at this kind of thing. For the most part, he's running rings around them. I don't know if this will have any long-term effect, but it's good for Obama and, regardless, a good show. Presidents should do this kind of thing more often.
