(Fox News) Hillary Clinton and Bernie Sanders clashed sharply Thursday over who is more progressive, at a debate that saw the former secretary of state ratcheting up her criticism of the Vermont senator on several fronts.
Clinton slammed Sanders' campaign promises as too costly and accused him of engineering an "artful smear" against her with suggestions that she could be "bought" by donors.
Sanders, meanwhile, dug in as he questioned her progressive credentials and described her as the candidate of the "establishment."

Clinton, though, questioned whether the candidate running to be the first female president can be part of the establishment, describing herself as a progressive who can "get things done."
