There’s no meaningful difference between republicans and democracts because both parties represent the interests of class that holds power in the end. And this isn’t just us Marxists saying this, here’s what a Princeton study analyzing many decades of US policy concluded:

What do our findings say about democracy in America? They certainly constitute troubling news for advocates of “populistic” democracy, who want governments to respond primarily or exclusively to the policy preferences of their citizens. In the United States, our findings indicate, the majority does not rule—at least not in the causal sense of actually determining policy outcomes. When a majority of citizens disagrees with economic elites or with organized interests, they generally lose. Moreover, because of the strong status quo bias built into the U.S. political system, even when fairly large majorities of Americans favor policy change, they generally do not get it.

US elections are just a circus with the sole aim of making people feel like they’re participating in the political process. Republicans are a brand curated to appeal to social conservative people and Democrats are a brand for socially liberal ones. The goal is to get people to get invested in issues that don’t threaten capital and to fight over them. As Parenti so aptly puts it in Blackshirts and Reds:

Seizing upon anything but class, leftists today have developed an array of identity groups centering around ethnic, gender, cultural, and life-style issues. These groups treat their respective grievances as something apart from class struggle, and have almost nothing to say about the increasingly harsh politico-economic class injustices perpe­trated against us all. Identity groups tend to emphasize their distinc­tiveness and their separateness from each other, thus fractionalizing the protest movement. To be sure, they have important contributions to make around issues that are particularly salient to them, issues often overlooked by others. But they also should not downplay their common interests, nor overlook the common class enemy they face. The forces that impose class injustice and economic exploitation are the same ones that propagate racism, sexism, militarism, ecological devastation, homophobia, xenophobia, and the like.
