"Despite being proven false, Donald Trump's 'Big Lie' about the 2020 presidential election being stolen from him keeps lingering over the American electorate, with its influence weighing heavily on voters just days before the midterms.
Some 40 percent of Americans believe that the 2020 presidential election, won by President Joe Biden, was rigged or stolen, a poll conducted by Redfield & Wilton Strategies on behalf of Newsweek found." --Newsweek, 11-2-22
The last time I looked 40% was a minority, not a majority. The survey said 40% "believed," the election was "rigged or stolen." That would be quite different from them "knowing," it had been done.
