What Americans think of Trump’s war on Iran

The American people are bitterly divided over the conflict in Iran. The US president, Donald Trump, won office in 2024 after campaigning on a message of “no new wars.”

So the conflict that began with airstrikes conducted with the Israeli military in the early hours of February 28, and which has quickly spread to the rest of the region, has polarized opinion across the country.

An Economist/YouGov poll completed on March 2 provides early information about what Americans think of the war so far. The poll asked the following question: “Would you support or oppose the US using military force to overthrow the government of Iran?”

There is a great deal of confusion about what the objectives of the war are, since the messaging from Trump and his senior officials has veered from preventing Iran from developing nuclear weapons, to destroying the country’s ballistic missile capability, to regime change.

But, from the point of view of polling, this is as good a question as any for finding out what Americans think. Altogether, 32% of them support the war and 45% oppose it.

A divided society

The responses to this question, analyzed by gender, race, age and education, appear in the graph. Those who were uncertain are not included in the totals. The graph shows that large variations exist among the different groups in relation to their attitudes to the war.

The relationship between attitudes to the war and the social backgrounds of respondents

The largest differences are in relation to race. Some 37% of white respondents support the war and 44% oppose it. In contrast, 7% of black people support it and 60% oppose. Hispanics were between these two, but closer to whites than to blacks.

There was a large gender difference in the responses as well, with 37% of men in support but only 26% of women. A marked age difference existed too with only 21% of 18-to-29 year olds supporting and 50% opposed.

At the same time, some 40% of those over the age of 65 supported the war, with 49% opposed. Finally, 34% of those without a college degree were in support compared with 27% with a college degree.

Overall, young black women with a college degree were most likely to oppose the war, whereas older white men without a college degree were most in support.

A question of politics

The social backgrounds and attitudes to the war of respondents are interesting, but they are overshadowed by the polarization of opinion among supporters of the political parties and ideological factions. These appear in the second chart.

The relationship between attitudes to the war and the political affiliations of respondents

The striking feature of this chart is the difference between respondents who identify with the Democrats and those who identify with the Republicans.

Only 8% of Democrats support the war compared with 64% of Republicans. The highest level of support comes from respondents who are MAGA (Make American Great Again) supporters. No less that 75% of them support the war and only 10% oppose it.

There is similar polarization among liberals, which refers to anyone on the left of the ideological spectrum in the US, and conservatives. Only 8% of liberals support the war compared with 66% of conservatives.

Moderates are in the middle, with 25% supporting and 50% opposing the war.

What it could mean for November’s mid-term elections

One theory of elections argues that individuals have a set of well-defined preferences over policies and so they support the party that is closest to them in relation to these policies. In this analysis, policy preferences are summarized by the left-right ideological dimension, or alternatively by the liberal-conservative dimension in politics.

In fact, it appears that in reality the reverse is true with voters choosing a party or leader and then changing their views to fit in with those of their newly adopted party. The 47th US president is an extreme case of this, because he constantly changes his mind.

Before he was elected, he promised that the US would not get involved in any more wars in the Middle East. It appears that most Republicans and nearly all the MAGA supporters are quite willing to go along with the U-turn and agree with anything he does.

This is a big advantage for a president who is so polarizing, since it means that he can rely on a body of loyal supporters even when they don’t know the latest policy changes.

However, it is a weakness when it comes to elections because the Democrats and Independents together easily outnumber the Republicans and MAGA supporters in the electorate.

The Cooperative Election Study, a large-scale survey conducted at the time of the presidential election in 2024, showed that 32% of respondents in their national survey identified with the Democrats, 27% with the Independents and 30% with the Republicans.

In short, the Republicans are up against a coalition of Democrats and Independents who make up just under 60% of the voters. Add the factor that many Americans are outraged by the president’s behavior and you have a winning coalition for the opposition in the midterm elections.

Whatever happens in the war, Trump is unlikely to recover his popularity for the Republicans not to lose control of the House of Representatives – and possibly the Senate – in the midterm elections in November.
