The United States Republican Party Nothing really substantial the way I see it. They are a party of pure reaction and do not really stand for "small governments" as much as they say they do. For example, most Republicans I've spoken to LOVE it when the government sends in an over-militarized police force to crush protestors or when as you said, the government helps a massive corporation recieve tax cuts to take the money away from "lazy welfare queens". The Republican Party is very much a fascist party in many ways (though fascism is extremely hard to define, and unlike Marxist traditions have a lot of whacky and contradictory thinkers) and they differ a lot from tea party libertarians who while still reactionary (in some sense) retain their fair share of political theorists to land on.
With the rise of groups like Qanon, the Proud Boys, etc and how they've been essentially endorsed by the Republicans during the Capitol attack, it's evident that the GOP only really believes in propagating fruitless, meaningless "culture wars" and retaining the myths of American exceptionalism without putting any thought into it. The contradictory nature of fascism was on full display too as seen from the recent banning of Critical Race Theory in school curriculums. Republicans go on and on about "FREE SPEECH" but are perfectly okay when bills are passed to erase essential history and sociology about the United States as a whole.
