McCain proposes a series of weekly "town hall" discussions between the presidential candidates, lightly moderated. Open questions, free-form. It's a great idea. Enough with Tim Russert, Brian Williams and the rest of the gasbags. Let the candidates thrust and parry. It also would seem to play into Obama's strengths, though there you begin getting into the expectations game. Sometimes you win, but lose by not winning by a wide enough margin. If the old man manages to be reasonably coherent, he might get a media A for effort.
