Biden leads Trump by 15 points nationwide.

Former Vice President Joe Biden has managed to gain dominant national leadership over President Donald Trump largely due to growing mistrust in the President’s handling of the coronavirus pandemic. The suspected Democratic candidate has a 15-point advantage (55 percent to 40 percent) over Trump among registered voters, according to a Washington Post / ABC News poll published on Sunday. That marks a five-point increase from May and a 13-point increase from March, when Biden only enjoyed a small advantage over Trump, as the coronavirus was just beginning to spread in the United States. Among likely voters, Biden’s lead drops to 10 points: 54 percent to 44 percent.

The poll still shows that despite positive numbers for Biden, the former vice president still faces several clear risks, namely that there is a significant lack of enthusiasm for his candidacy. But that may not really matter because the vast majority of Biden’s supporters view elections as more about beating Trump than choosing Elect Biden. In fact, voters on both sides of the aisle see the November election as a referendum on Trump more than anything else. Among Biden’s supporters, 67 percent say defeating the president is the most important factor in the election, while 72 percent of Trump voters say they consider reelection of the president the most important thing.

The biggest advantage for Biden comes as Americans increasingly trust the former vice president about Trump in handling the coronavirus pandemic. Biden leads Trump on who voters trust to deal with the coronavirus at a whopping 20 points: 54 percent to 34 percent. When the question is about who voters trust in the economy, Trump continues to lead, from 47% to 45%, albeit by a markedly narrower margin than in March, when he enjoyed an eight-point lead on the issue. Overall, approval of the way Trump has been handling his job as president has been on the decline and now stands at 39 percent, representing a nine-point decrease since March.

The Washington Post / ABC News poll released Sunday is the fifth consecutive high-quality national poll that shows Biden ahead of Trump by at least 10 points, Politico notes. That’s a historic advantage and marks the widest margin for a challenger since Bill Clinton. That is due in large part to the coronavirus, but also because Biden’s long career has made it difficult for the Trump campaign to discover an effective line of attack that can help negatively define the alleged Democratic candidate.
