DURHAM, N.H. (Reuters) - Democrat Hillary Clinton went on the attack against rival Bernie Sanders on Thursday in their most contentious presidential debate yet, questioning whether his ambitious proposals were viable and accusing him of an "artful smear" in suggesting she could be bought by political donations.
Sanders fought back repeatedly, questioning Clinton's progressive credentials and portraying her as a creature of the political establishment in a debate that featured heated exchanges on healthcare, college tuition funding and efforts to rein in Wall Street.
