Democratic presidential nominee Hillary Clinton leads Republican Donald Trump by 15 percentage points among early voters surveyed in the past two weeks, the Reuters/Ipsos States of the Nation project finds.

Though data is not available for all early voting states, Clinton enjoys an edge in swing states such as Ohio and Arizona and in Republican Party strongholds such as Georgia and Texas, according to Reuters.

An estimated 19 million Americans have voted so far in the election, according to the University of Florida’s United States Election Project, accounting for as much as 20 percent of the electorate.

Overall, Clinton remained on track to win a majority of votes in the Electoral College, the Reuters/Ipsos survey showed.

The poll was conducted before the FBI's announcement on Friday that it is examining newly discovered emails belonging to Clinton’s close aide, Huma Abedin.

Those emails were found on a computer belonging to Anthony Weiner, Abedin’s estranged husband, during an unrelated investigation into illicit messages he allegedly sent.

It remains unclear whether the FBI inquiry will upset the balance in the race, noted Reuters. The FBI disclosed nothing about the Abedin emails, including whether any of the messages were sent by or to Clinton.

Over the summer, the FBI said it was closing its investigation into Clinton’s use of a private email system while serving as Secretary of State.

Before the FBI announcement, Clinton has held a lead averaging four to seven percentage points in polls in recent weeks as the Trump campaign wrestled with accusations by women of inappropriate behavior. Trump has stressed that none of the accusations are true.

As of Thursday, Clinton’s odds of receiving the 270 Electoral College votes needed to win the presidency remained at greater than 95 percent, according to State of the Nation polling results released Saturday. The project estimated she would win by 320 votes to 218, with 278 votes solidly for the Democrat.
