Hillary Clinton maintains a lead over Donald Trump, but lagging interest among some of her supporters poses a potential turnout challenge for Democrats with less than nine weeks before Election Day, according to a new Washington Post-ABC News poll.

Clinton holds a 46 percent to 41 percent edge over Trump among likely voters, followed by Libertarian candidate Gary Johnson at 9 percent and the Green Party’s Jill Stein at 2 percent.

Clinton’s lead swells to 10 percentage points among the wider swath of registered voters, 45 percent to 35 percent, similar to her 45 percent to 37 percent edge last month.

The findings come at a time when the margins between Clinton and Trump have narrowed in some battleground states and when some national polls also have shown a tightening in the competition. Heading toward the first presidential debate on Sept. 26, though, Trump still appears to have the more challenging route to victory.

Both candidates’ reputations have been battered by the campaign, with more than 6 in 10 voters saying each candidate is not honest and trustworthy, and with majorities critical of Clinton’s ethics as secretary of state as well as Trump’s qualifications and his behavior toward women and minorities.
