Washington: Hillary Clinton, presumptive Democratic presidential nominee, has been shown as having a nine point lead over her Republican rival Donald Trump in a latest survey by nonpartisan American think tank.
In the survey, four-in-ten voters said it is difficult to choose between them because neither would make a good US president.
In a two-way contest, 51 per cent of registered voters support presumptive Democratic presidential nominee Clinton, 68, or lean towards her while 42 per cent support or lean towards presumptive Republican presidential nominee Trump, 70, Pew Research Center said in its latest survey on Friday.
However, the overall satisfaction with the choice of candidates is at its lowest point in two decades, it said.
Currently, fewer than half of registered voters in both parties, 43 per cent of Democrats and 40 per cent Republicans, say they are satisfied with their choices for president, the survey said.
Roughly four-in-ten voters (41 per cent) say it is difficult to choose between Donald Trump and Hillary Clinton because neither would make a good president, as high as at any point since 2000. Just 11 per cent say the choice is difficult because either would make a good chief executive, the lowest percentage during this period, it said.
The survey was conducted between June 15-26 among 2,245 adults, including 1,655 registered voters.
According to survey results, just 27 per cent of Americans say the campaign is "focused on important policy debates", which is seven points lower than in December, before the primaries began.
Clinton holds a wide 66 per cent-24 per cent advantage among Hispanic voters.
This is on par with President Barack Obama's lead among Hispanics at similar points in the past two campaigns.
When it comes to the issues at the forefront of voters' minds, the economy tops the list, with 84 per cent of voters - and similar shares across most demographic and political groups - saying it is very important to their vote.
About as many (80 per cent) say the issue of terrorism will be very important to their vote, the survey said.
Clinton is widely viewed as more personally qualified and possessing better judgement than Trump, it said.
"However, neither candidate has an advantage on honesty: 40 per cent say the phrase "honest and truthful" better describes Clinton, 37 per cent say it applies more to Trump and 20 per cent volunteer that it better describes neither candidate," it said.
As per survey results, fully 77 per cent of voters say Trump would change the way things work in Washington, compared with just 45 per cent who say the same about Clinton.
"But more voters say Trump would change things for the worse than for the better (44 per cent vs 33 per cent).
A quarter of voters say Clinton would change Washington for the worse while 20 per cent say she would change things for the better," the survey added.
