Honestly, probably yee haw anarchism. I firmly believe that most Americans are more receptive to anarchist ideology than MLism. This is a somewhat biased take considering it's based on where I grew up, which was rural and super anti-government; maybe things are different for city natives. Even then there's municipal :LIB: ertarianism, though, which I've often found people to be very receptive to because it seems superficially benign.

Other potential aspects:

• Absolute rejection of traditional leftist icons like Marx or Kropotkin. Lots of gross praise for (and recharacterization of) founding fathers.
• Mandatory public service after high school. Not necessarily with the military; would likely see options for industrial work, possibly as a way to cut down on infrastructure costs, and also an option for fighting the massive fires that continue to appear every summer. Rich kids would somehow get an exception.
• Continued struggles with immigration issues.
• Increasingly decentralized agriculture, with municipalities beginning their own agricultural production efforts.
• Public housing that sucks and is poorly maintained, but probably more of it. People who live in public housing are still stigmatized.
• Drugs. Lots of drugs.
• Religiosity, free speech, and firearms.
• Bitter conflict with the Southern states, which resent the new form of government and are always on the verge of forming a breakaway.
• Universal healthcare that is expensive as shit because there's a public option but medicines/other medical technologies are still produced privately and sold to the government at inflated costs.
