...they are Nihilists
You can't be a hypocrite if you don't have foundational values to betray, and Republicans in thrall to MAGA are proving that they only value will to power, which is the will toward illusion and chaos. They would nominate and vote for Jeffrey Dahmer if they thought he would get them a senate majority. They will say anything and do anything to achieve that end. It's no more complicated than that. They might justify this by telling themselves that as soon as they obtain complete power they'll impose their god-and-nation values on the American political system.
And so some decent moral-traditionalist Republicans are vulnerable to be seduced by the god-and-nation rhetoric because they don't understand that "god" is a placeholder symbol for Chaotic Power, and "nation" is a placeholder symbol for the Mob, and the Mob is always a conduit for the darkest and most evil impulses humans are capable of. The Mob might think that its actions are justified by the god in whose name it acts, but that god is an idol, a fabrication, a delusional mist, an egregore. And the god-and-nation rhetoric is a fog of delusions that will at some point dissipate to reveal the evil, i.e., the destructive chaos, i.e, the 'Nihil' that it enshrouds.
So I'm tired of Liberal pundits pointing to MAGA Republican hypocrisy as if somehow to do so was to shame them into some form of moral consistency, to get their actions aligned with what they profess. This is an exercise in sanctimonious futility. It gives MAGA Republicans more credit for having a moral compass than they deserve. What they profess has nothing to do with their deepest beliefs because, in fact, they believe in Nothing.
These people seduced by MAGA are not themselves evil, but to the degree that they are swept up by the Mob, they become ciphers, empty vessels for evil. I still retain hope that there is enough substantive decency and discernment in moral-traditionalist Americans that they will resist this seduction into idolatry. If enough don't, Nihilism will likely win in the short run.
The good news is that Nihilism always loses in the end. Nothing cannot sustain itself on Nothing. The Living Real will reassert itself. It just seems that we must learn this over and over again the hard way.
BTW, Liberals and the Cultural Left are vulnerable to be seduced by the other prominent contemporary form of Nihilism, which is Neoliberalism. Neoliberals don't run in a mob because they control all most of the institutional power, including the McConnell wing of the GOP establishment. The GOP has become essentially the party of Neoliberal elite Nihilists trying to get in front of the MAGA Nihilist parade. While Nihilism and will to power play a role in the Democratic Party, the Dems are not completely captured by it in the way that the GOP is. The GOP is bereft of good faith, whereas there is still plenty of good faith and basic decency among important Democratic leaders, among whom I'd list Joe Biden, Bernie Sanders, Elizabeth Warren, Sherrod Brown, AOC, Pramila Jayapal (my rep), Chris Murphy, and several more. Agree with them or disagree with them, they are good-faith actors in a way that GOP leaders are not. Most non-Nihilist Republicans have either quit or been voted out, and if they remain in office, unless they are governors or mayors, their influence is inconsequential.
