Trump leads Harris (48 percent to 47 percent) in the poll, which has a margin of error of 3 percent.

The race remains largely unchanged, the New York Times reported in July, when Harris replaced President Joe Biden on the Democratic ticket, citing a poll he had released at the time.

Trump "may have had a difficult month following the president's departure and amid the burst of enthusiasm the vice president brought to the Democratic ticket," the report says, adding, "the poll suggests his support remains remarkably resilient." .

The race is equally tied in the seven battleground states surveyed by the New York Times, with Harris ahead of Trump or tied (50 percent - 47 percent), Michigan (49 percent - 47 percent), Pennsylvania (49 percent percent - 47 percent), - 48 percent), Nevada (48 percent - 48 percent), Arizona (48 percent - 48 percent), Georgia (48 percent - 48 percent) and North Carolina ( 48 percent - 48 percent).

The vice president leads the former president 48.1 percent to 46.7 percent in the average of national polls calculated by RealClearPolitics and 47.3 percent to 44.2 percent in the weighted average from FiveThirtyEight national polls.

Harris and Trump hold their first presidential debate Tuesday in Philadelphia. There are no other debates scheduled as of yet, so this may be the first and only debate of this cycle.

With early elections beginning in many states this month and less than 60 days remaining before voting closes, whether by mail or in person on Nov. 5, neither candidate has the luxury of time to reverse a setback. That will be especially true for Harris, who faces his biggest test yet in this race on Tuesday.

Understanding what's at stake, Harris has largely stepped back from the campaign trail and has been in Pittsburg, Pennsylvania, since Thursday preparing for the debate.
