About a third of US voters supporting Democrat Hillary Clinton and Republican Donald Trump are doing so primarily because they dislike the other candidate, a poll released Wednesday found.
The Pew Research Center survey found 33 per cent of Trump supporters say their main reason for supporting him is that he is not Clinton, while 32 per cent of Clinton supporters say they support her because she is not Trump.
The same percentage of Clinton supporters also list her political experience as the main reason to vote for her, while 27 per cent of Trump's supporters chose him because he is a political outsider they believe will bring change and 26 per cent list his policy positions.
The non-partisan centre characterizes the views as signs of a negative campaign and notes the majority of supporters of both candidates express concerns about their own candidate. Trump supporters are worried about his character and personality and Clinton supporters are concerned about her honesty or her associations with outside businesses or groups.
Only 11 per cent of respondents said they would be excited if Trump wins the November 8 presidential election, while 12 per cent said they would be excited if Clinton prevails.
Pew surveyed some 4,500 adults in the poll from August 16-September 12 with a margin of error of plus or minus 2.4 percentage points.
