Harris and Trump Deadlocked to the End, Final Times/Siena National Poll Finds

Kamala Harris and Donald J. Trump are locked in a dead heat for the popular vote, 48 percent to 48 percent, the final national poll by The New York Times and Siena College has found, as Ms. Harris struggles for an edge over Mr. Trump with an electorate that seems impossibly and immovably divided.

The result, coming less than two weeks before Election Day, and as millions of Americans have already voted, is not encouraging for Ms. Harris. In recent elections, Democrats have had an edge in the popular vote even when they have lost the Electoral College and thus the White House. They have been looking to Ms. Harris to build a strong national lead as a sign that she would do well in such critical swing states as Michigan, Pennsylvania and Wisconsin.
