PHILADELPHIA — Meet the new Hillary Clinton, repackaged and updated from previous versions. But will voters notice or care? After decades in the public eye, Clinton is being presented to Americans again at the Democratic convention in Philadelphia, this time as a barrier-breaking liberal champion who fights for families and children. But even as Democratic Party stars delivered one testimonial after another this week, some voters watching from the convention floor said they already know Clinton, or think they do, through her years as first lady, senator and secretary of state, and not all views are favorable.
