US Democratic presidential nominee Hillary Clinton�s lead over her Republican rival Donald Trump has reached 8 points following both parties' presidential nominating conventions, a new poll shows.

According to the Washington Post-ABC News poll released on Sunday, Clinton� now leads Trump 50 percent to 42 percent among registered voters.

The survey, carried out August 1-4, shows a twofold increase from what the Democrats held on the eve of the Republican convention in mid-July.

Clinton also leads Trump 51 percent to 44 percent among likely voters who have not registered to vote yet, according to the poll.

With regards to a four-way race, which includes Libertarian Party nominee Gary Johnson and Green Party nominee Jill Stein, the fomer secretary of state is ahead of Trump 45 percent to 37 percent, with Johnson having 8 percent and Stein 4 percent, the poll indicates.

She enjoyed a four percent lead in a four-way matchup before the Republican convention.

The new poll is indicative of the fact that Clinton got a larger post-convention boost compared to what Trump received from his convention.

The survey also shows that 74 percent disapprove of the way�Trump treated a Muslim American family whose son, Army Captain Humayun Khan, was killed in Iraq in 2004.

Trump said that Ghazala Khan, the mother of the soldier, was silent during her husband�s speech at the DNC because she was not �allowed� to speak.

The poll also shows that�registered voters are unhappy with both Clinton and Trump.

�Almost 6�in 10 registered voters say they are dissatisfied with the choice between Clinton and Trump as the major-party candidates, virtually unchanged from mid-July,� according to�the poll.

A Gallup survey�last month showed that�27 percent did not trust Clinton, 13 percent did not like her and eight percent considered her as a �criminal� or a �corrupt� person.

About Trump, sixteen percent disliked him, 12 percent described him as an "idiot" or a "joke" and 10 percent as a "racist" or a "bigot," the poll showed.
