The poll found that Hillary Clinton leads Donald Trump by just 4 points nationally, 48% to 44%. The Democratic nominee led by 12 points as recently as this weekend.
Libertarian candidate Gary Johnson had 4% support and Green Party’s Jill Stein had 1%.
Trump’s jump in support is thanks to Republican-leaning and independent voters.
And the Republican nominee is making up ground with women as well. In the last poll, white women favored Clinton 49% to Trump’s 43%. But in Friday's results, they now back Trump, 48% to 43%.
Trump also leads with political independents by 12 points.
The poll was conducted Oct. 23-26 of 1,150 likely voters, and the margin of error is plus or minus 3 points.
