Your verbatim claim is that "More than half of this nation know that the election was stolen."
Your own citation presents data to prove that this claim is untrue.
Here is an excerpt from the Guardian article you cite:
"The 17-19 May national poll found that 53% of Republicans believe Trump, their party’s nominee, is the “true president” now, compared with 3% of Democrats and 25% of all Americans.
About one-quarter of adults falsely believe the 3 November election was tainted by illegal voting, including 56% of Republicans, according to the poll. The figures were roughly the same in a poll that ran from 13-17 November which found that 28% of all Americans and 59% of Republicans felt that way."
Can you read?
Or, did you get someone to help you?
If the later, have them help you with this statement: "28% of all Americans and 59% of Republicans felt that way."
Do you think truth is some sort of rhetorical game? ...and that the "side" which cheers loudest -- and lies most -- determines what Truth is?
"Trump Lies Shamelessly, Compulsively, Continuously... And His Followers Suck The Sludge"
