Is the post-presumptive-nominee bump over? Mccain led obama twice - once when he non-officially became the nominee, and once during convention.
NEW YORK, June 3 (Reuters) - Democratic presidential contender Hillary Clinton has opened up a double-digit lead over Republican rival Donald Trump, regaining ground after the New York billionaire briefly tied her last month, according to a Reuters/Ipsos poll released on Friday.
The shift in support comes as Clinton steps up her attacks on the real estate mogul's policy positions, and as Trump fends off criticisms of his eponymous university and the pace at which he doled out money that he raised for U.S. veterans.
Some 46 percent of likely voters said they supported Clinton, while 35 percent said they supported Trump, and another 19 percent said they would not support either, according to the survey of 1,421 people conducted between May 30 and June 3.
