70 percent of Republicans now say they don’t believe the 2020 election was free and fair, a stark rise from the 35 percent of GOP voters who held similar beliefs before the election.
Among Republicans who believed that the election wasn’t free and fair, 78 percent believed that mail-in voting led to widespread voter fraud and 72 percent believed that ballots were tampered with — both claims that have made a constant appearance on the president’s Twitter thread. Like President Donald Trump, a majority of the people that thought the election was unfair, 84 percent, said it benefited Biden.
