I never watch cable news, or tv news of any kind, unless there's some special event - and then it's usually c-span (on youtube, I don't have cable). The impressions I get are from online interaction (which I hope to God isn't an accurate generalization) and/or what I see in NYT, WaPo, Atlantic, or occasionally other similar editorial sources. Or when Reuters or AP News covers a quote. And I'm not saying that having hardcore Republicans tell the truth about the election (those who are being accused of being RINOs because they won't go along with the Big Lie, when it couldn't be further from the truth) is going to convince even most of the Trumpublican cult any time soon. But there have to be people on the fence. There must be people who believe it simply because they're surrounded by others who have absolute conviction in it, and slow and steady exposure to the truth will make them question who's right (which is almost always the case - since the truth will continue to be the truth no matter how hard the GOP spins "election fraud", it will ultimately also be the most consistent, and calm people do eventually take notice of that). Having big Republican names like Liz Cheney standing behind it puts a dent in the "it's partisan propaganda" argument they're using. When those people on the fence start to come around, then the power of conviction contagion will start spreading in the opposite direction. (Very, very slowly, but still).
Honestly, the only Republican I personally know who is even willing to openly express disappointment currently with the party is highlander. About 2/3 of the Republicans (at least they were prior to this past 5 years) I personally know aren't willing to talk about it, at all, and I get the impression they're being a lot quieter than they used to be because they really can't figure out what the fuck is going on. Then maybe 1/3 of the other Republicans I know are the usual belligerent, railroading assholes that vomit out spastic deflection and bullying discourse (in the guise of "debate"). I have to assume the squeakiest wheels in current discourse are not representative of the entire base who voted for Trump (and therefore, aren't as irredeemable as those types seem to be).
I mean, it's honestly soothing to have people like Joe Walsh, George Conway, Tom Nichols, and others on Twitter constantly point out the clear propaganda. It's a reminder that hotly disagreeing with someone about only policy is exponentially less infuriating than witnessing how the entire GOP media bubble and nearly the entire GOP elected base is flat out lying.
