US President Donald Trump’s approval rating has dropped to a new low, according to a Washington Post-ABC News-Ipsos poll, as the Iran war drives higher prices and economic uncertainty.

The survey found Trump’s overall approval at 37%, down two points from February, while his disapproval rose to 62%, the highest of his two terms.

Republican support remains strong at 85%, while 56% of Republican-leaning independents said they approve of his performance.

However, approval among independents has fallen to 25%, described as a new low for that group.

The poll also shows growing dissatisfaction with Trump’s handling of the economy, with only 34% approving of his economic management and 33% approving of his handling of the Iran war.

Inflation and rising fuel prices linked to the conflict have contributed to higher living costs.

The consumer price index rose 3.3% in March compared with a year earlier.

A separate AP-NORC poll also showed low approval figures, with 30% on the economy and 32% on the war.

The survey of 2,560 adults was conducted between April 24 and 28.

Overall, the results show a divided public, with 34% trusting Republicans, 33% trusting Democrats, and the remainder expressing no preference or trust in either party.

With six months to go before the midterm elections, the data suggest potential challenges for Republicans holding narrow majorities in Congress, with Democrats holding a small lead in congressional voting preference.
