Republican voters are so far into the sunk cost fallacy of their cult, they are more than willing set themselves on fire, so long as their ENEMIES burn with them.
To me, that’s the quintessential difference between the modern American centrist party (we don’t have a meaningful left with any power sadly) and right wing party: Most of us want Republicans to have access to healthcare they can afford, utilities that work, safe food and water, and education, we all know they fucking need that last one desperately.
Modern Republicans, on the other hand, would very much like if those that opposed them (or are even just minding their own business but don’t align with the rigid tenets of their cult) were dead, preferably very painfully while they watch.
Note all the obnoxious signs on many of their homes openly “jokingly haha” pining for the opportunity to shoot someone who gets too close to their properteh.
