For years, Donald Trump's political strength has rested on a simple advantage: even when his wider approval numbers fall, his core Republican supporters have tended to remain firmly behind him. Now, that loyalty is showing a small but notable crack.

For the first time in NBC News Decision Desk polling, fewer than half of Republicans say they strongly approve of Trump's performance as president. The survey, conducted from 20 August to 1 September, found that 41% of Republicans strongly approved of Trump's job performance. That was down from 52% in a similar survey conducted from 30 March to 13 April.

Among voters who identify as MAGA, strong approval also fell. It dropped from 71% in the spring to 62% in the latest poll. The figures do not show Trump losing the Republican Party. But they raise a different question: how intense is the support that remains?

Trump's Overall Republican Support Remains High

The distinction is important. While strong approval has fallen, 80% of Republicans still said they approved of Trump's performance when both strong and less intense approval were counted. Among MAGA supporters, the overall approval figure reached 93%.

That means Trump's political base remains considerably more supportive of him than the wider electorate. His overall approval rating, however, has fallen to 36% in the NBC poll. That is one percentage point below the spring figure. The change comes as Republicans prepare for the November midterm elections, when control of Congress will be at stake.

Rising Costs Add to the Pressure

The polling comes against a difficult economic backdrop. American motorists are facing significantly higher fuel prices, with the national average for regular petrol at about $4.15 a gallon on 7 September, according to AAA. Diesel prices have risen even further. AAA's latest figures put the national average at about $5.88 a gallon.

Fuel prices have become particularly sensitive because the conflict with Iran has disrupted energy markets and raised concerns about supplies and shipping through the Strait of Hormuz. For voters, those pressures are not abstract. They appear in household budgets, commuting costs, and the price of moving goods across the country. That gives economic conditions a direct political impact.

Another Poll Shows Voter Anxiety

The NBC findings are reinforced by a separate Financial Times poll conducted by Focaldata. That survey found that only 33% of registered voters approved of Trump's performance, the lowest figure recorded in the poll since it began asking the question in May. Approval among Republican voters also fell, reaching 72%.

The poll found deep concern about the economy. Almost two-thirds of respondents said they believed the economy was moving in the wrong direction, while 57% said they were financially worse off under Trump's presidency. The findings point to a broader problem for Republicans.

Trump remains popular within his party, but economic concerns could make it harder for Republican candidates to separate their campaigns from the president's record.

Midterms Create a New Test

The timing of the polling matters. The November elections are approaching, and Republican candidates will need to mobilise Trump's supporters while also appealing to voters concerned about prices, jobs, and the economy.

Recent reporting from the Financial Times has also highlighted growing concern among Republicans that Trump's low approval could damage candidates in competitive races. For now, the polling does not suggest that Trump's Republican coalition has broken apart. The stronger conclusion is more measured.

His supporters remain largely behind him, but fewer Republicans now express that support with the same intensity they did earlier this year. That could prove important in an election where turnout and enthusiasm may matter as much as broad party loyalty. Trump's challenge, therefore, is not simply to keep Republicans on his side. It is to keep them strongly convinced that his presidency is delivering what they expected.
