Just 41 percent chose Clinton, the presumptive Democratic nominee.

The poll surveyed 1,000 adults, including 750 who said they were likely to vote in the November election, from June . The margin of error is 3.6 percentage points among likely general election voters and is 3.1 points for all adults. Additional questions were added after the Orlando shooting Sunday morning.

The poll was conducted after Trump said an Indiana-born federal judge overseeing lawsuits against Trump University may be biased against him because of the judge's Mexican heritage. The poll found that 55 percent of likely voters were very bothered by those comments.

The poll shows a wider lead for Clinton than most other polls. Clinton leads Trump by 4.5 points in the RealClearPolitics average of polls.
