Six out of 10 South Carolina Republican primary voters think Biden wasn’t legitimately elected

Exit polls show election denialism has become mainstream among Republicans despite studies finding no widespread fraud in 2020

More than 60% of South Carolina Republican primary voters said they don't believe Joe Biden was legitimately elected, according to exit polls, the latest data point that underscores how election denialism has become a mainstream belief in the Republican party.

Eighty-seven percent of those who don't believe the US president was legitimately elected supported Donald Trump, according to a CNN exit poll of South Carolina primary voters. Just 12% supported Nikki Haley. Among those who believe Biden legitimately won in 2020, the results were nearly flipped 81% supported Haley, while 19% supported the former president.
