The people who run the USA are not divided. They do not care what the general public want. The main factions are the limousine Left, represented by the ruling elite in the Democrat Party, and the Left fascists, who promote a Marxist friendly form of racism in the name of fighting racism and are trying very hard to overthrow the present government. For the most part, the limousine Left of the Democratic Party use these Left fascists in much the same way they once used the Ku Klux Klan and other white supremacist groups - as a militant faction to suppress dissent and to engage in extra-legal punishment of their political enemies, such as small business owners.
The limousine Left has their vision of the future, which will secure the power of this group for at least two or three generations. The rebellion of Trump, a long time Democrat supporter of the Clintons, demonstrated less the power of the Right so much as their irrelevance (a rebellious Democrat was literally able to take over their party). The victory of the Affordable Care Act and many other policies, and the complete impotence of the Trump administration underlines the utter powerlessness of Republicans and the tax peasants who support them. The January 6th "insurrection," which was so brutally and successful put down compared to the months of similar "mostly peaceful" riots, looting, arsons and murders of their Left fascist equivalent demonstrate the utter powerlessness of the alt-Right. During the Trump administration, the State Department simply ignored the instructions of the executive branch. The public school monopoly, dead set against charter schools let alone school choice, ostracized the Department of Education under Betsy DeVos. Black Lives Matter went out of their way to support the segregated school system enforced by the public schools. And so on.
It doesn't matter what you want. It matters what the main players want. The limousine Left wants to keep and expand their power base. The Left fascists want to overthrow the limousine Left. The Republicans are being co-opted by a rival Democrat family to the Clintons. The Democrats will continue to win elections, if necessary by creative vote counting and fast tracking illegal immigrants to battleground regions. The Left fascists will try to confound this process, but whenever they engage in unauthorized violence they will be treated like the Proud Boys. And that is that.
George Carlin had a good approximation:

Remember that the real purpose of socialism, right from the very beginning is and always has been the enrichment and empowerment of a small socialist elite, all at the expense of everyone else. The end state is something called "managerialism." For further details on what this system is and how it relates to the evolution of modern economies and politics, see "The Managerial Revolution" by James Burnham.
It's good that so many people here are RPG veterans, because this makes it easy to explain the mindset of the limousine Left. Did you ever run a high level party that "owned" a region of the gaming world? If a player got hurt or died, they would get the best healing potions and magic possible or get resurrected, regardless of the cost. Indeed, some of their gear cost more than the annual wealth output of whole villages. Your players might have been benevolent, or perhaps ran their peasant mobs like the players in KODT, but regardless they felt they were doing the best for "their" people. Any alternate forms of power would be identified and crushed, and a convenience excuse contrived, because those high level players knew what was best for their peasants. Perhaps they kept a convenient group of hounds or orcs or whatnot around, just in case the peasants got restless and needed a lesson in obedient servitude. And so on. Kinda like Arthur and Co in Monty Python and the Holy Grail. Or like modern Cuba or Nicaragua.
So no balkanization, unless the high level players start fighting over the loot. And unless you figure out real fast how to get into power as a Democrat member of Congress or a Democrat governor, you're going to get to roleplay one of the tax peasants. Won't that be fun. Enjoy.
