The two-day poll found Republican presidential candidate Trump opening a marginal lead among registered voters - 43% to 41% - over Democratic US President Joe Biden, an advantage that was within the poll's 3 percentage point margin of error, suggesting the attempt on Trump's life had not sparked a major shift in voter sentiment.
But 80% of voters - including similar shares of Democrats and Republicans - said they agreed with a statement that "the country is spiralling out of control." The poll, which was conducted online, surveyed 1,202 US adults nationwide, including 992 registered voters.
Trump narrowly avoided death on Saturday when a would-be assassin's bullet grazed his ear as he spoke at a campaign rally in Pennsylvania. Blood trickled across his face and he defiantly pumped his fist in the air, mouthing the words "Fight! Fight! Fight!" as he was rushed offstage. A rally attendee was slain and two others seriously injured.
The shooting brought back memories of turbulent political periods such as the 1960s, when Democratic President John F. Kennedy was assassinated in 1963, followed by the killing of Democratic presidential candidate Robert F. Kennedy in 1968.
Some 84% of voters in the poll said they were concerned that extremists will commit acts of violence after the election, an increase from the results of a Reuters/Ipsos poll conducted in May that showed 74% of voters having that fear.
Fears of political violence became more prominent in America after thousands of Trump supporters attacked the US Capitol on Jan. 6, 2021, in a bid to overturn Trump's election loss to Biden. Four people died on the day of the attack, and one Capitol Police officer who fought against the rioters died the next day.
While Americans said they feared violence, few condoned it. Just 5% of respondents said it was acceptable for someone in their political party to commit violence to achieve a political goal, down from 12% in a Reuters/Ipsos poll from June 2023.
Some 67% of respondents in the latest poll said they were concerned about acts of violence against their community because of their political beliefs, compared to 60% in a Reuters/Ipsos poll from June 2023. Bipartisan majorities in the latest poll said they were concerned Americans could resort to violence instead of coming together peacefully to solve disagreements.
The attempt on Trump's life has dominated media headlines and fuelled discussion among some of his conservative Christian supporters that he was protected by God.
In the Reuters/Ipsos poll, 65% of registered Republicans said Trump's survival showed he was "favoured by divine providence or God's will." Eleven percent of Democrats agreed.
The United States stands out among rich nations for its embrace of religion, with evangelical Christians largely aligned with the Republican Party in recent decades. Some 77% of Americans surveyed in 2022 said they believed in God, compared to 56% of Canadians and 39% of British respondents, according to a poll by the Gallup International Association.
