Republican presidential nominee Donald Trump's decline in support over Democratic candidate Kamala Harris on issues such as the economy and crime has been confirmed in a new Reuters/Ipsos poll.

The results of the poll, conducted between August 23 and 25, show that 43 percent of respondents prefer Trump's approach to the economy and jobs, while 40 percent side with Harris.

A difference of 3 percent is too small, given the survey's margin of error of 4 percentage points. In a Reuters/Ipsos poll late last month, Trump had an 11 percent lead on economic policy.

Support for Harris and Trump regarding the topics of crime and corruption is equal - 40 percent each. By comparison, the Republican leader led by 5 percent in the July poll.

The latest national polls show Harris with a slight lead over Trump after she entered the race on July 21 following President Joe Biden's decision to suspend his campaign. In a Reuters/Ipsos poll from late July, Harris leads Trump by one percentage point (43% to 42%).

It remains to be seen how independent candidate Robert F. Kennedy Jr. suspending his campaign will affect the race. Kennedy Jr., who had an 8% approval rating in July, said Friday that he was backing Trump.

The latest Reuters/Ipsos poll shows the economy is the biggest issue for 26 percent of registered voters. In second place, with 22 percent, is political extremism and threats to democracy, and 13 percent of those surveyed indicate immigration as a basic problem.

Respondents who prefer Harris' approach to fighting extremism are 42 percent, while Trump has the support of 36 percent of those polled on the issue.

As for immigration policy, 45 percent of those polled approve of the Republican leader's approach, while 37 percent support the Democratic Party's candidate.

Neither candidate enjoys widespread public popularity – 59 percent of voters said they had an unfavorable opinion of Trump, while 52 percent of respondents said the same about Harris. She is favorably perceived by 47 percent of voters, compared to 39 percent for Trump.

The Reuters/Ipsos poll was conducted among 1028 adults from across the country, 902 of whom are registered voters.
