It's clear that opening the debates isn't what some folks want to see... Take a look at what Hillary Clinton and John Edwards think about limiting debate, when they think the microphone is off:

After the forum, microphones picked up Clinton and Edwards discussing their desire to limit future joint appearances to exclude some rivals lower in the crowded field. “We should try to have a more serious and a smaller group,” Edwards said. Clinton agreed. “We’ve got to cut the number. … They’re not serious,” she said, then thanked Obama and Ohio Rep. Dennis Kucinich as they walked by. Turning back to Edwards, she added that she thought their campaigns had already tried to limit the debates and “we’ve gotta get back to it.”

Et tu, Hillary? This doesn't really jibe with your answer to us... so what is the truth here? Are you really not merely ambiguous, but secretly opposed to opening debates?
