Clinton confronts rival Sanders as Iowa polls tighten

WATERLOO, Iowa (AP) — Hillary Clinton has spent much of her presidential campaign looking past Democratic rival Bernie Sanders, focusing instead on Republicans and the November general election. No longer.
Three weeks before the lead-off Iowa caucuses and with polls suggesting a tightening race, she now is confronting the Vermont senator more directly, attempting to undermine his liberal credentials on gun control, health care and even the Wall Street regulations that have been the core of his insurgent campaign.
