Brett Kavanaugh, whose hearings began Tuesday morning, has the support of 38 percent of Americans in the poll, while 39 percent say the Senate should vote him down. The support levels registered in the poll are the third-lowest of any nominee to the Supreme Court in the poll's history.

Harriet Miers and Robert Bork, two unsuccessful nominees in 2005 and 1987, respectively, were the only Supreme Court nominees to score lower than Kavanaugh.

Twenty-three percent of Americans remain undecided on Trump's nominee, according to the poll.

The split opinion comes as Democrats are hitting the GOP for moving on Kavanaugh's nomination without many of the documents from his time serving in the George W. Bush White House.

But Republicans can confirm Kavanaugh on the Senate floor without any Democratic support.

Kavanaugh was nominated in July to the Supreme Court following the announcement of Justice Anthony Kennedy's retirement. The nomination is Trump's second as president, following the successful naming of Neil Gorsuch to the court last year.

The same poll found Democrats taking a double-digit lead over Republicans on a generic House ballot, with Democratic voters generally more enthusiastic about voting as well.

The Washington Post/ABC News poll was conducted between Aug. 26-28 and surveyed 1,500 registered voters. Its margin of error is 3.5 percentage points.
