Donald Trump's approval rating has fallen to 31 per cent, the lowest of his two terms, two weeks before Americans vote in congressional midterm elections on 3 November.
The figure comes from a four-day Reuters/Ipsos poll that closed on Monday. It is one point lower than the same poll found a fortnight earlier, as voters named fuel prices and the cost of living as their main concerns.
Asked how they would vote if the elections were held that day, 47 per cent of registered voters chose the Democrats and 35 per cent chose the Republicans. The 12-point gap is the widest Democratic lead in the poll this election cycle and puts both the House of Representatives and the Senate in play.
The survey was conducted online with 1,679 American adults, including 1,279 registered voters. The margin of error is 2 percentage points for all respondents and 3 points for registered voters.
Other polls released in recent days point the same way. A Washington Post-ABC-Ipsos survey published on Monday put Trump's approval at 33 per cent, with seven in ten respondents saying petrol was becoming unaffordable, while an NBC poll on Sunday found 71 per cent thought the country was on the wrong track and 55 per cent would vote Democratic.
Trump's standing has slid since the United States and Israel launched a war on Iran on 28 February, which pushed up petrol and diesel prices and fed through to the wider economy. He spent Monday campaigning for Republican candidates in Kansas.
Generic ballot questions measure national sentiment and do not decide individual House and Senate races, where district boundaries and local contests shape the result. Republicans still hold structural advantages in several states.
