WASHINGTON (TIP): With 52 days left to the big day, Hillary Clinton leads Donald Trump by five points in a head-to-head matchup in the latest national poll of likely voters from Quinnipiac University released Wednesday, Sep 14, but the margin has been chopped in half since the last time the poll was released in August.

Clinton was ahead of Trump 48%-43% in a head-to-head matchup with likely voters nationally on Sep 14. (In a survey released in late August, Clinton had 51% and Trump was at 41%.) Regardless of whom they are supporting, majority of the voters were supporting their candidate because of the opponent rather than liking their choice.

More than half-54 percent of Clinton supporters said opposing Trump was their main reason for backing the Democratic nominee. Approximately two-thirds of likely Trump voters-66 percent-said their main reason for supporting him is because they opposed Clinton.

The latest results come as other state and national polls show similarly tightening margins between both major candidates, who have traded words in recent days over concerns about transparency and health.

The Quinnipiac poll began last Thursday, Sep 8, a day after the Commander in Chief Forum, and remained active in the field until Tuesday, Sep 13, after days of public attention on Clinton’s health following her early departure from a 9/11 memorial on Sunday and subsequent revelation that she had been diagnosed with pneumonia.

When third-party candidates were included in poll, Clinton and Trump were separated by just 2 points, which is within the margin of error.

CLINTON HAD 41%, TRUMP HAD 39%, LIBERTARIAN PARTY CANDIDATE GARY JOHNSON HAD 13%, AND THE GREEN PARTY’S JILL STEIN CAME IN AT 4%.

Trump led with white voters by 10 points (51%-41%), while Clinton was ahead with non-white voters 66%-19%.

Trump led with men 50%-41%, while Clinton led with female voters 54%-36%.

TRUMP LEADS CLINTON IN NEW OHIO, NEVADA, FLORIDA POLLS

The Republican nominee is enjoying a 5-point lead in Ohio in a new Bloomberg Politics poll. In a head-to-head matchup between Clinton and Trump, he led 48%-43%.

The margin remained the same when third-party candidates were added. Trump had 44%, Clinton had 39%, Libertarian Gary Johnson had 10% and Green Party candidate Jill Stein had 3%.

The Bloomberg Politics poll was taken over some of Clinton’s most difficult days of the cycle.

She said “half” of Trump’s supporters were “deplorable” Friday night, and on Sunday she wobbled as she left a 9/11 memorial, while recovering from previously undisclosed pneumonia.

Trump’s lead in Ohio is consistent with a CNN/ORC poll of likely voters released Wednesday which had him at 46%, Clinton at 41%. Johnson had 8% support and Stein had 2%.

Trump was also ahead in Florida in the CNN/ORC poll – though the 3-point difference fell within the margin of error. Trump had 47%and Clinton had 44%. Johnson had 6% and Stein had 1%.

And in Nevada, Trump had a 2-point lead over Clinton – also within the margin of error – in a new Monmouth University poll released Wednesday.

Trump had the support of 44% of likely voters in Nevada, while Clinton had 42%. Johnson had the backing of 8%; Stein was not included.
