Mark Penn, chief pollster for Hillary Clinton's 2008 presidential campaign, tells ABC that had John Edwards chosen not to run because of the whole affair-and-babymaking thing, "it would have been a very different race," because Edwards voters were "focused on demographics" and Hillary would have been their other white meat. "We will never know for sure," says Penn, for whose sterling services Clinton still owes $2.3 million, "but it will be the woulda, coulda, shoulda of this race." Or, you know, one of them.
