Hillary Clinton leads Donald Trump by four points: Poll

The latest 'Wall Street Journal/NBC News poll' found that 44% of the likely voters support 69-year-old Clinton

Democratic presidential nominee Hillary Clinton leads her Republican rival Donald Trump by 4% points, a latest national opinion poll said on Sunday, two days ahead of the crucial US general elections.

Clinton, who has maintained lead over Trump ranging from 1% to as high as 12% in most of the opinion polls after the two back-to-back conventions in July, faces the toughest political battle of her life from the real estate billionaire who is less than 18 months old in politics.

The latest 'Wall Street Journal/NBC News poll' released on Sunday found that 44% of the likely voters support 69-year-old Clinton while Trump is supported by 40%.

Another 6% support Libertarian candidate Gary Johnson and 2% support the Green Party candidate Jill Stein.

In a mid-October, the poll conducted by The Wall Street Journal /NBC News, Clinton had a commanding lead of 11% points.

The drop of 7% points is seen as an effect of the decision of the FBI last week to re-open its investigation against her alleged email scandal, following which the popularity of Trump has surged.

"Much of the change from mid-October comes from Trump winning an increased share of the vote within his own party, which brought him on par with Clinton's support among Democrats," The Wall Street Journal said.

The poll was conducted between November 3 and 5 among 1,282 likely voters.

It has a margin of error of plus or minus 2.73% points.

According to RealClearPolitics, Clinton is leading by 1.8% points in its latest average of major national polls.

According to Politico/ Morning Consult poll released on Sunday, Clinton is leading by just three points and is supported by 45% of the likely voters.

"While our final poll before the election shows a tight race, Clinton has maintained her small lead in our polling for weeks now," said Morning Consult co-founder and chief research officer Kyle Dropp.

"There is little that could swing voters now in the final hours leading up to Election Day," Dropp said.

The poll surveyed 1,482 likely voters and has a margin of error of plus or minus 3% points.
