Some 57% of likely voters intend to vote for Biden, while just 40% say they will vote for the incumbent president, the survey shows.
The 17-point gap is even bigger than 57%-41% margin found by CNN earlier this month. It is just short of the lead in the popular vote that Ronald Reagan enjoyed in his second landslide victory in 1984. Four years later, Democratic nominee Michael Dukakis led George HW Bush by 17 points only to suffer defeat, but that poll was taken in July so Bush had ample time to recover.
With election day just three weeks away and millions of votes already cast, some Republicans fear a rout in the races for the presidency, Senate and House of Representatives. Ed Rollins, who advises a pro-Trump super political action committee, told the New York Times: “The president’s political environment is terrible. It’s an uphill battle.”
Opinium’s findings for the Guardian suggest that a hectic month that saw the death of the supreme court justice Ruth Bader Ginsburg, Trump’s disastrous debate performance and a White House outbreak of coronavirus that infected the president himself swung the pendulum decisively in Democrats’ favour.
Biden has gained five percentage points among undecided voters since September. Democrats also injected momentum into existing supporters, with voters for Biden now more likely to turn out, up from 75% in September to 82% this month.
