NEW YORK - A new poll shows about three out of four Americans believe Donald Trump will further divide the country if elected, but doubts remain about Hillary Clinton's ability to unite as well.

The survey released Monday by The Associated Press-NORC Center for Public Affairs Research found only about a third of people think Clinton, the Democratic nominee, would help unify the country. But that's twice the share received by Trump, the Republican nominee.

Some 85 per cent of people say they the U.S. is more politically divided than in the past. Eighty per cent view Americans as greatly divided on the most important values.

The poll of 1,008 adults was conducted June 23-27 -- before the political conventions. The margin of error for all respondents is plus or minus 4.1 percentage points.
