Clinton leads Trump 46-to-43 percent in a NBC News/Wall Street Journal poll, compared to a similar one in April in which Clinton had an 11-point lead.
The new poll also shows Clinton primary rival Vermont Sen. Bernie Sanders leading Trump by 15 percentage points, 54-to-39 percent, in a hypothetical November matchup.
“Polls this far out mean nothing,” Clinton said on NBC’s “Meet the Press.” “They certainly mean nothing to me. And I think that if people go back and look, they really mean nothing in terms of analyzing what's going to happen in the fall.”
Earlier Sunday morning, a Washington Post/ABC News poll showed voters favored Trump over Clinton 46-to-44 percent. The numbers also show Clinton losing an identical 11-point lead since earlier this spring.
Both polls were within the statistical margin of error, which means Clinton and Trump are essentially tied.
Trump said on the Fox News Channel’s “Fox & Friends Weekend” show that he suspects some of the support is coming from Sanders’ backers, now that their candidate faces very long odds in winning the Democratic nomination.
“I hear and I look at polls, and I hear a lot of those people are coming with us,” Trump said in a phone interview. “A lot of the Bernie Sanders’ voters, they do not like Hillary Clinton. … A lot of those people will come with me.”
The Washington Post/ NBC poll also shows a majority of the electorate has an unfavorable impression of Clinton, a former secretary of state, and Trump, a billionaire businessman, and that likely voters are “motivated as much by whom they don’t like as by whom they do.”
According to The Washington Post: “Never in the history of the Post-ABC poll have the two major party nominees been viewed as harshly as Clinton and Trump.”
The NBC/Wall Street Journal poll reported voters also have record-low opinions of those two candidates.
“Trump and Clinton are currently the two most unpopular likely presidential nominees in the history of the NBC/WSJ poll,” the pollsters said.
