Democrats opportunistically weaponized the pandemic to unlawfully change election rules, paving the way for now-President Joe Biden to be declared the winner of the Nov. 3 race, according to a six-month investigation of the 2020 presidential election.

In a 23-page report, the Republican National Committee’s election integrity panel stated, “Democrats and their liberal allies, including some elected officials, exploited the pandemic and used it as an excuse to haphazardly expand mail voting and loosen important integrity measures that are broadly supported by Americans and which prevent irregularities.”

While these rules changes “may have been well-intentioned, they were unnecessary,” the report concluded.

The findings were first reported on Thursday by the Washington Examiner’s Paul Bedard.

According to investigators, the following groups bypassed state legislatures and illegally changed state election rules in the leadup to the 2020 presidential race: “courts that disregarded long-standing laws, by Democratic governors who abused their emergency powers, and by officials such as secretaries of state who ignored state laws duly passed by their legislatures.”

These last-minute rules changes compromised election security and made the process highly vulnerable to voter fraud, according to the RNC report.

After making the case for mass mail-in voting, Democrats “watered down verification processes in order to handle the influx of absentee ballots,” the report found.

“This included lowering review standards for counting ballots and insufficient ballot duplication procedures.”

The report also found that Republican poll watchers were “stonewalled” in several Democrat-controlled districts, preventing them from doing their job — which was to ensure that vote-counting was not done in secret.

“Some officials also stonewalled access of Republican poll watchers and observers, and withheld access to basic election information the parties and public should reasonably expect to have,” the report asserted.

Because of these underhanded tactics, according to the RNC, Democrats eroded election integrity.

“These attacks on transparency and the rule of law significantly undermined voter confidence in the election system,” the report noted.

While some accommodations had to be made because of the pandemic, Democrats used the crisis “as a pretense to achieve long-sought policy goals such as expanded mail voting and the elimination of key safeguards, specifically for absentee voting, such as witness and ID requirements,” the report stated.

“One of the worst examples is the automatic mailing of ballots to voters who did not request them, including in states such as New Jersey and Nevada that had no tradition of heavy absentee voting and were unprepared to scale up their processes,” the report noted.

“Another example was how state courts ignored laws enacted by their legislatures such as ballot delivery deadlines.”
