Did Trump voters vote for deporting every undocumented immigrant?

I’ll cut to the chase: No.

We as Americans do have the habit of being selective about how we describe the motivations and priorities of voters. Most people cast their ballots in support of candidates from the party with which they agree, rather than engaging in a complicated analysis and ranking of policy positions. (This, in fact, is a central reason that political parties exist!) When a candidate loses or wins, however, they — and their supporters — and their detractors! — often ascribe the victory or loss to specific things that they advocated or opposed. If they ran on putting billboards on the Washington Monument and were elected because their opponent was caught on video abusing a puppy, the now-inaugurated candidate will happily inform the public that they must put a Pepsi logo on the National Mall because it’s What The Voters Wanted.™

Over at Bluesky today, there was a little flurry of a debate over the extent to which supporters of Donald Trump’s 2024 candidacy were explicitly supportive of the sweeping deportation effort that’s now underway. One side of the debate argued that Trump (and his surrogates) spoke frequently about deporting millions of people; there had even been signs at the convention reading “Mass Deportation Now.” The other side noted that conventions are only rarely considered by the voting public, and that many people voted for Trump for reasons that had nothing to do with any promises about deportation. (Like, for example, inflation.)

Again, the latter argument is correct. And we know that because Trump voters themselves indicate that they oppose the sort of deportations that are underway.

Even before Trump took office in January, polling showed a wide gap between support for deporting any immigrant who was living in the country without proper authorization and deporting those who’d committed crimes. The specific numbers depended on the wording of the poll (see results from AP-NORC and the Wall Street Journal below), but the gap was consistent: Far more people endorsed narrower deportation efforts than broader ones.

Those numbers weren’t broken out by party, however. So let’s look at June polling from YouGov, which presented various deportation scenarios to respondents.

Again, we see that deportations of immigrants convicted of crimes enjoys wide support. But support declines under different circumstances. Only a quarter of Americans — and only half of people who say they voted for Trump last year! — support deporting immigrants who have kids that are citizens. Less than half of Trump voters support deporting people who’ve lived in the country for years without committing crimes.

I’ll note that this doesn’t mean that half of Trump voters oppose deporting people who’ve lived in the U.S. for years without committing crimes. In fact, only a third do; the other 20 percent say they aren’t sure if such people should be deported.

But it is clearly not the case that Trump voters supported sweeping deportation of immigrants regardless of circumstance back in June. From that, it follows that it is unlikely that most of them supported such a sweeping deportation strategy last November, when they were casting their ballots. Some did, yes. But it’s very unlikely that most did.

I’ll add one last thing. While I was still at The Washington Post, I occasionally wrote about Trump’s deportation policies and looked for images from the convention of people holding those “Mass Deportations Now” signs. As it turns out, this was not easy to do. They were not ubiquitous or constant; I believe (and am happy to be corrected) that they were trotted out for only one part of one night.

Meaning that while they came to represent Trump’s position in the eyes of his opponents, it’s probably not the case that they represented the views or understanding of most of his supporters.
