Donald J. Trump continues to march to the 2024 Republican presidential nomination with a commanding lead over his primary rivals, even as a strong majority of voters nationwide believe he has committed serious federal crimes, including a growing faction of Republicans, according to a new poll from The New York Times and Siena College.

The results show the remarkable degree to which Republican voters are willing to look past Mr. Trump’s legal jeopardy — the former president has been indicted four times in 2023 and faces 91 felony counts — and line up behind his potential return to power.

Overall, 58 percent of voters nationwide believe Mr. Trump committed serious federal crimes, according to the survey, including 66 percent of independent voters.

Yet Mr. Trump continues to clobber his closest Republican competitors in the primary by more than 50 percentage points, pulling in the support of 64 percent of Republican primary voters nationwide. Nikki Haley, the former United Nations ambassador, is now in a distant second place, with 11 percent, followed by Gov. Ron DeSantis of Florida, who has fallen to third, with 9 percent.
