The fact that the election was valid and not subject to any sort of widespread fraud was widely reported news. Over and over again, we heard (even from republicans such as Bill Barr) that the Biden win was legitimate.In their minds, they were trying thwart an attempt to formalize fraudulent election results. Thus, they would be preventing the installation of an illegitimate regime.
Someone to maintaining the lie that the election was "stolen" is not merely some ignorant but well-meaning rube who got tricked, but a person who either knew that the election was valid (but just didn't like the result), or someone who has gone out of their way to deny reality.
