Hillary Clinton, buoyed by a dominating win in South Carolina on Saturday, is opening a dual-track strategy in her bid for the White House, gradually pivoting toward Republicans even as she works to expand her lead across more than a dozen states voting this week.<br />Clinton's campaign, feeling more confident than it did after a narrow win in Iowa and a double-digit defeat in New Hampshire, has started to evaluate how it would run against the now smaller Republican field and what each candidate would mean for Clinton.<br />Looking ahead, Clinton's aides know they are not going to knock Sanders out on March 1, but they hope by the end of the night on Tuesday - where 865 delegates are at stake - their campaign will have at least a 100 earned delegate lead over the Vermont senator.
