“It’s my greatest concern, my single greatest concern: This president is going to try to steal this election.”

What keeps Joe Biden awake at night? As a presidential candidate, many matters could weigh heavy on his mind. The Democratic candidate is most concerned, however, that President Donald Trump will try to cheat his way to victory in November, Reuters reported.

Military Will Intervene, Biden Says

In a Wednesday evening interview on Comedy Central’s “The Daily Show,” Biden told host Trevor Noah that even if he loses, he may refuse to vacate the White House willingly.

“It’s my greatest concern, my single greatest concern: This president is going to try to steal this election,” Biden said. If Trump loses and refuses to leave, Biden is “absolutely convinced [the military] will escort him from the White House with great dispatch.”

He referenced recent comments from top military officials, current and former, as evidence that the military would make the right call to protect democracy, ABC News reported. 

“You have four chiefs of staff coming out and ripping the skin off of Trump, and so many rank-and-file military personnel saying, ‘Whoa, we’re not a military state. This is not who we are,’” Biden said.

Vote-by-Mail Initiatives Under Scrutiny

Although Biden did not point to any specific tactics Trump may use to cheat, he did suggest that Trump’s opposition to mail-in voting could be a method designed to suppress voter turnout.

“This is a guy who said that all mail-in ballots are fraudulent, voting by mail, while he sits behind the desk in the Oval Office and writes his mail-in ballot to vote in the primary,” he said.

Due to the coronavirus pandemic, more voters than usual are expected to cast mail-in votes. Ahead of the Georgia primary on Tuesday, 1.2 million voters requested absentee ballots, up from 40,000 in 2016.

The Republican Party and Trump have made attempts to discourage states from permitting absentee voting on the basis of the health pandemic, however. In the case of Michigan and Nevada, the president threatened to revoke funding because the former decided to provide ballot applications by mail for all registered voters and the latter decided to hold an entirely mail-based election.

Voting by mail is not unusual, however, and prior to this year, five states used it an exclusive means to vote.

In an attempt to preempt possible voter suppression attempts from Trump or the GOP, Biden said his campaign is assembling a legal apparatus to ensure voting is conducted legally and fairly. Democrats, he said, will have layers at polling places nationwide to be on alert for malicious tactics.

McEnany Responds: ‘Ridiculous’

Trump has yet to respond to Biden’s interview comments, but White House Press Secretary Kayleigh McEnany touched on them during a Fox News interview Thursday morning.

“I think that’s a ridiculous proposition. This president is looking forward to November, this president is hard at work for the American people. Leave it to Democrats to go out there and grandstand and level these conspiracy theories,” McEnany told Fox News Thursday morning.

Tim Murtaugh, communications director for the Trump campaign, responded by calling Biden’s comments “another brainless conspiracy theory” designed to “undermine confidence in our elections.” He also stated that Trump would accept the election results.

Biden’s worries about how Trump will handle the 2020 election and its results are based on the president’s behavior after the last presidential election, Reuters reported. During a debate with his opponent, Democratic candidate Hillary Clinton, Trump dismissed the idea that he would concede Clinton’s victory if the results were in her favor. 

Following the election and Trump’s victory, he went on to allege that illegal voters had delivered Clinton the popular vote. Trump said as many as five million illegal voters helped sway the popular vote for Clinton, who won by almost 3 million votes, BBC reported.

“In addition to winning the Electoral College in a landslide, I won the popular vote if you deduct the millions of people who voted illegally,” Trump tweeted.

After taking office, he created an election integrity commission headed by Kansas Republican gubernatorial candidate Kris Kobach. The panel was disbanded less than a year later after producing no reports or evidence of voter fraud in the 2016 election.
