It’s one of the biggest questions in the wake of Donald J. Trump’s conviction: Did the verdict change anyone’s mind?

Early on, the answer appears to be an equivocal “yes.”

In interviews with nearly 2,000 voters who previously took New York Times/Siena College surveys, President Biden appeared to gain slightly in the aftermath of Mr. Trump’s conviction last week for falsifying business records.

The group favored Mr. Trump by three points when originally interviewed in April and May, but this week they backed him by only one point.

While there’s no way to be sure whether their views reflect the broader electorate, the findings offer unusually clear evidence that the verdict has led some voters to reconsider their support for Mr. Trump.

Overall, Mr. Trump retains 93 percent of voters who told us they backed him in a previous survey — a tally that’s yet another striking show of political resilience from a candidate who is facing three more sets of criminal indictments.
