There are no deniers on the right.
“There are no deniers on the right”. So you have spoken with everyone who identifies as a Republican/Conservative about this ..???
I suspect there are many Republican/Conservatives that do not share your view. I also think that many Republicans don’t think the election was stolen but remain silent lest they incur the wrath of those who are true believers who believe it was stolen.
Just look at how people respond to any dissent about the election fraud, criticism about Trump, or anything that challenges the narrative.
