An American polling company has found a high number of Democrats believe their party won the presidency through unlawful means.

The latest Rasmussen Reports survey about the initial outcome of the presidential election caught nearly a third of Democratic Party supporters openly admitting Joe Biden stole the Oval Office away from incumbent President Donald Trump.

Almost a third of Democrats who responded believed the party unlawfully removed and destroyed pro-Trump ballots in several states to make sure Biden won.

“Huge: ‘How likely is it that Democrats stole votes or destroyed pro-Trump ballots in several states to ensure that Biden would win?'” the company said on Twitter. “Democrats—30 percent to 20 percent say very likely (VL), unaffiliated—39 percent to 29 percent say VL, Republicans—75 percent to 61 percent say VL, [and] all voters—47 percent to 36 percent say VL.”

Nearly half of the 1,000 people surveyed, 47 percent, agreed that the Democrats “stole votes or destroyed pro-Trump ballots in several states to ensure that Biden would win.”

“This includes 36 percent who say it is very likely,” Rasmussen said on its website. “Republicans say it is very likely the Democrats stole the election … [and] among unaffiliated, 29 percent feel it is a stolen election.”

Rasmussen also found an overwhelming majority of respondents believe President Trump should wait until legal challenges to the election outcome have run their course before considering whether to congratulate Biden on winning the election.

“Eighty percent of voters who do not believe Trump should concede yet think it is very likely Democrats stole votes or destroyed pro-Trump ballots in several states to ensure that Biden would win,” the company said. “Fifty-seven percent of Republicans disagree [that it is time for the president to concede defeat].”

The company conducted the survey between Nov. 17 and Nov. 18. The data includes a sampling error margin of “+/- 3 percentage points with a 95 percent level of confidence.”

Rasmussen revealed President Trump’s legal challenge is appealing to an increasingly younger demographic that does not believe he should concede defeat. More white people agreed the president should continue to contest the election results, while African Americans and other minority groups agreed to a lesser degree.

Less than a quarter of Trump supporters believe the incumbent should “admit he lost.”

“Looking back at the presidential election, Trump voters overwhelmingly say they voted for the president, while a sizable number of Biden supporters admit they were voting against Trump rather than for the former vice president,” Rasmussen said.
