Hillary Clinton's national lead over Donald Trump has disappeared, thanks to a huge advantage Trump has with independent voters who may have shifted after several weeks of bad news for Clinton, according to a new national poll.

In a CNN/ORC poll released Tuesday morning, the Republican presidential nominee leads Clinton by 2 points among likely voters — 45-43. That's a virtual tie in a poll with a 3.5 percentage point margin of error, and it erases Clinton's 8-point lead that she had in the same poll in early August.

The shift took place after it was found that thousands of additional Clinton emails were discovered from when she was secretary of state, emails she tried to destroy. Additionally, the FBI released notes of its conversations with Clinton that showed she wasn't aware of when emails were marked confidential.

Ninety-two percent of Democrats back Clinton and 90 percent of Republicans back Trump. But Trump has a big lead among independents: 49 percent say they back Trump, and just 29 percent back Clinton.

Trump also leads among men, 54-32. But women support Clinton 53-38, and Clinton also leads 54-29 among people younger than 45. Trump leads the pack among those older than 45, 54-39.

Similar to other national polls, white voters pick Trump (55-34), while Clinton has roughly 4 times the support among non-whites than Trump (71-18).

The telephone-based poll of 1,001 adults was conducted Sept. 1-4 with a margin of error of plus or minus 3.5 percentage points. The samples include 886 registered voters and 786 likely voters.
