Republican presidential nominee Donald Trump and his Democratic rival, incumbent Vice President Kamala Harris, are nearly tied in the final weeks before the election, according to a poll by the New York Times and Siena College.

Trump leads by one percentage point — 48 percent to 47 percent — over Harris, a poll released today showed, a narrow margin that could mean victory for both candidates in the Nov. 5 election.

Although Trump's campaign went through a relatively difficult period after Democratic President Joe Biden withdrew from the race in July, recent polls show that he still has the support of regular supporters.

The poll showed voters feel they need to know more about Harris, while their opinions of Trump are already formed.

In the poll, 28 percent of likely voters said they needed more information about the Democratic nominee, while just 9 percent said the same about Trump. The poll also suggests that Tuesday's presidential debate could represent a turning point.

Harris will get a chance to give more details about her policy plans as she debates Trump for 90 minutes. The poll shows the race is so close that even a marginal increase for either candidate could mean a lot.

Key figures from the latest poll are similar to one published in late July by the New York Times and Siena College, which had Trump leading by one percentage point. Polls in seven key states that are likely to determine the winner also consistently show narrow margins.
