America’s voting system came under further scrutiny after the Trump administration released evidence that appears to show an election irregularity.

President Donald Trump has gone public about the unusually high jump in votes for Democratic rival Joe Biden one day after the presidential election, on Nov. 4.

Individual time-stamped entries from Wisconsin clearly show the incumbent had a comfortable lead against Biden until the early morning hours after Election Day.

“Trump was leading above 51 percent all night and then lost the lead with the data dump,” the voting tally chart said in a screenshot shared on Twitter. “Data dump giving Biden 143,379 votes at 3:42 a.m.”

The Oval Office was not impressed by the “miraculous increase” in the number of votes.

“Look at this in Wisconsin! A day after the election, Biden receives a dump of 143,379 votes at 3:42 a.m., when they learned he was losing badly,” the president said on Twitter. “This is unbelievable!”

More than half of Republican Party supporters surveyed shared the president’s disappointment because they also believe the Democrats stole the election through widespread voter fraud.

The latest Reuters/Ipsos opinion poll found 52 percent of Republicans believed President Trump “rightfully won” the election between Nov. 13 and 17.

In contrast, only 29 percent of Republicans believed Biden had rightfully won the presidency. The rest expressed suspicion about exactly how the Democrat had been unofficially declared the winner by mainstream media instead of the official Federal Election Commission.

Sixty-eight percent of Republicans complained about the election being “rigged,” while 16 percent of Democrats and a third of independents expressed similar concerns.

The poll also found Americans seem to be more suspicious about this election process than about the 2016 general election.

A total of 55 percent of American adults believed the latest presidential election was “legitimate and accurate,” representing a 7 point decrease from a similar poll that ran shortly after the previous election.

The 28 percent of voters who said the election outcome was the product of “illegal voting or election rigging” jumped 12 points compared to the previous election.

In comparison, 52 percent of Democrats said former Democratic presidential nominee Hillary Clinton’s loss to President Trump was “legitimate and accurate” back in 2016. Only 26 percent of Republicans thought the incumbent’s unofficial loss was legitimate and accurate in 2020.

The Reuters/Ipsos poll was conducted online in English across the United States. It gathered responses from 1,346 respondents, including 598 Democrats and 496 Republicans, with a credibility interval, a measure of precision, of 5 percentage points.
