President Donald Trump is trailing former vice-president Joe Biden by 10 points in a hypothetical 2020 presidential election, says a new poll from Fox News. The survey was released late Thursday evening and found that Biden and Sen. Bernie Sanders beat President Trump in their head-to-head matchup, with Sanders having a 6 point lead over Trump.

Fox News interviewed 1,004 randomly chosen registered voters nationwide between July 21 and 23 for the survey. It was conducted under the joint direction of Beacon Research and Shaw and Company. The margin of error is 3 percent and Biden’s is the only lead outside the poll’s margin of sampling error.

According to the hypothetical 2020 election results, 49 percent voters favored Biden, while 39 percent chose to vote for President Trump. The survey shows that voters' opinions regarding Biden-Trump matchups were largely unchanged.

According to the poll, Biden captures 33 percent support among the Democratic primary voters and is the lone top tier candidate in the Democratic nominations race. He has almost double the votes of other presidential hopefuls. Biden is followed by Bernie Sanders (15 percent), Elizabeth Warren (12 percent) and Kamala Harris (10 percent).

As reported in Politico, President Trump renewed his attacks on Fox News Friday in the aftermath of the poll results, saying that the pollsters in the network weren’t favourable enough to him. He also claimed that the news organization had been proud warriors for him in the run-up to 2016 elections.

Trump argued that there was no way he would be losing to the "sleepy one" (Biden) as he believed the American economy had strengthened under his watch.

Trump had previously praised another poll by the news channel, which had found that President's ratings had slightly increased, the past week. And despite his complaints he phoned into the Sean Hannity’s show Thursday night for a 25-minute long conversation.

Apart from the matchups, the polls found that 56 percent of the Democratic primary voters believed that voting for a candidate who can beat Trump was more important while 41 percent were in support of one who can change fundamentally how the economy functions.

Biden was the top choice for those supporting winning, while Biden and Sanders were chosen equally by those who prioritized economic change.
