What would it mean if Wisconsin decertifies the 2020 election?

"Fair and honest elections are the cornerstone of our democracy and we know that the 2020 presidential election was neither fair, nor transparent,” Brandtjen said in a news release posted on Facebook. "Tyranny is at Wisconsin’s door."
Brandtjen said she would join fellow state Rep. Tim Ramthun, a Republican candidate for governor, in pushing to overturn the last presidential election and dismissed the naysayers. "We have been told for months now that decertification is impossible, meaning there is no downside to cheating in Wisconsin elections," Brandtjen said. "How many more times do we need to endure this election injustice?"
