You're just projecting OTL viewpoints into TTL.
Political punditry is going to be a very different beast.
How would TTL political pundits in Red America behave?
I tend to imagine Red Americans as being like OTL Americans, just painted red: they believe they are greatest motherfuckers who ever lived, and that all should aspire to be them. Albeit this attitude is probably more justified than OTL American exceptionalism.
Here is what Red America has that OTL America does not.
1. A national history that can genuinely lauded.
The founders of the UASR managed to avoid most of the pitfalls of political revolution: dictatorial backsliding, a crazed totalitarian ruler, bad economic policies. They effectively created a workers' state after beating back a cabal of corrupt capitalists that chose their power and money above the freedom they claimed to laud.
Granted, they are guilty of a lot of shit, but they did settle down and play nice
2. They pulled the USSR away from its autocratic madness.
I think TTL historians might think the real turning point in history was the execution of Lavrentiy Beria.
More so than the downfall of the tsar or MacArthur's flight, this might be the moment that changed the very concept of revolution: that revolutionaries could not break the rules they wrote.
But making the USSR into a more democratic nation, rather than a bastard child of Marx and Catherine the Great, is certainly something to laud.
3. Crushing the Axis powers.
Self-explanatory.
4. Building a truly equal nation of all its peoples.
Erasing the self-destructive bigotry that plagued America for centuries and expanding opportunities for Blacks and other minorities is definitely something to laud.
5. Assuring personal freedom on things like drugs, sex, and reproductive rights.
Red Americans have a lot to be genuinely proud off. But could this pride lead to "Muricanism in the opposite direction? An arrogant belief in their own superiority, and a preachiness that aggravates others.
