WASHINGTON, June 14 (UPI) -- A new poll shows Hillary Clinton leading Donald Trump by double digits nationally and by a two-to-one margin, with voters saying Trump has become less appealing to them the longer he's campaigned.

The poll, conducted by Bloomberg News, shows Clinton leading nationally, 54 percent to 36 percent. Nine percent of respondents said they were unsure for whom they will vote.


When pollsters included the name of Libertarian Party candidate Gary Johnson in the list of candidates alongside Clinton and Trump, Clinton's support slipped to 49 percent with Trump's 37 percent. Johnson claimed 9 percent support, with fewer voters saying they were not sure who they would support when his name was included.

When asked whether a candidate was becoming more or less appealing as the campaign has gone on, Trump's numbers show a marked slide in popularity. Sixty-four percent of likely voters said they found Trump less appealing than they did at the start of his campaign, while just 33 percent said they liked him more.

Clinton was under water in that category, as well, but by a much smaller margin: 51 percent like her less, and 46 percent like her more.

The Bloomberg survey is the most favorable one, by a wide margin, for Clinton of those released recently. Other polls have shown her leading Trump, but by between three and eight percentage points nationally.

The Real Clear Politics polling average for surveys taken since late May, which includes the Bloomberg survey, shows Clinton with a lead of 5.5 percentage points nationally.

The Bloomberg poll was completed from June 10-13. It surveyed 750 likely voters and carries a margin of error of 3.6 percentage points.
