Well, as the article explains, it's evolved. Now, Carson wants to limit debate time and debate nature by adding more time for beginning and ending statements, by each candidate, and Cruz wants the Republican debates to be only moderated by those who are registered Republicans. This might help some of them from clarifying, actually hiding, their policy positions and plans, for the Republican primaries, but it's going to set them up for failure if Hillary wins the Democrat primaries, since, given her command of policy positions and plans, and her significant experience and communication skills, she will make toast out of any Republican who is afraid of a "gotcha question."
