More than half of voters continue to give President Donald Trump strong approval ratings as he approaches the end of his first 100 days in office.

His sustained popularity—particularly among independent voters—is reflected in high marks for his handling of key issues like reducing illegal immigration and cutting government spending.

A large survey of 2,286 registered voters—conducted by Harvard’s Center for American Political Studies, The Harris Poll, and HarrisX and released Monday—found that 48% still believe President Trump is the right leader for the moment.

In comparison, 46% disapprove of his performance, while 6% remain undecided or have no opinion.

“Trump’s approval is still above water but has dipped four points,” pollsters wrote, noting “Trump’s highest approval is on his handling of immigration and reducing (government) costs, while his lowest is on tariffs and inflation.”

Just over half of those surveyed—51%—support Trump’s immigration policies, consistent with previous findings that show broad approval for his long-standing push for mass deportations.

The issue made headlines Monday when both Trump and El Salvador’s President Nayib Bukele said they would not assist in extraditing an alleged MS-13 gang member from a Salvadoran prison back to Maryland, where he was recently apprehended.

Meanwhile, 50% of respondents also back Trump’s efforts to “reduce the cost of government,” a signature initiative led by advisor Elon Musk and the U.S. Department of Government Efficiency.

A combined 56% of respondents say President Trump is performing either better than expected or about as expected. The results highlight both achievements and challenges in the early months of Trump’s second term, as he pushes forward with plans for the largest mass deportation operation in U.S. history—an initiative prompted by record-high levels of illegal and asylum immigration during the Biden-Harris administration.
