WASHINGTON - As her rival for the US Democratic presidential nomination racked up another victory, Hillary Clinton on Sunday dismissed the notion of a contested party convention and said she was not preparing for such a scenario.Bernie Sanders won the Wyoming caucuses on Saturday, beating Clinton in seven out of the last eight Democratic nominating contests as the two gear up for a crucial matchup in New York.The US senator from Vermont is trying to chip away at Clinton's lead in the number of delegates needed to secure the party's nomination for the Nov. 8 presidential election.He said on Sunday that he could close the gap, and left the door open for a so-called floor flight at the Democratic National Convention in July if neither has won an outright majority of delegates.In that case, a system of multiple ballots takes place governed by complex rules, with candidates hoping to convince delegates to vote for them.Asked on CNN if she were preparing for such a scenario, Clinton said, "No, I intend to have the number of delegates that are required to be nominated."Clinton said she was leading Sanders by 2.5 million popular votes and in pledged delegates. "I feel good about the upcoming contests, and I expect to be the nominee," she said.The Wyoming results did not change the delegate math for the Democratic contenders. Each won seven, since delegates are awarded proportionally based on caucus-goers support.Going into Wyoming, Clinton had more than half of the 2,383 delegates needed to win the nomination. Sanders trailed her by 250 pledged delegates, those awarded based on the results of the state nominating contests.But Sanders said future contests in the West and East Coast looked favorable to him, including New York, Pennsylvania, California and Oregon."We believe that we have the momentum. We believe that the polling is showing that we're closing the gap," Sanders said on ABC's "This Week."
