I think we have the opposite going on here - the conservatives are breaking the system in such a way, that it must change. This is the big chance for a 3rd party to destroy the old guard, simply because the old guard is being incredibly dumb and greedy with their own overhaul.
It is simply a question of who can offer the better future. The wealthy dudes who are going to kill grandma by taking away her medicine and money, or the nice lady who wants granny to live a long and decent life?
The Avatar episode about No War in Ba Sing Se would fit in as well. Oh, and the opening episodes of the classic Battlestar Galactica - the Cylons attack when the opposition is gathered for a peace conference. We might relate if WW3 starts.

We probably should make a list of stuff for everybody to select and show for their respective libraries.
*Avatar: The Last Airbender, episode 14, "City of Walls and Secrets".
*Babylon 5: seasons 4 and 5 focus on the civil war with Earth. In one of the episodes, Sheriden asks incoming warships about what they are supposed to do when issued illegal orders. We could use a supercut of B5 that is solely concerned with the civil war, since the series is filled with many unrelated plot threads.
On that note, Mac's Lore did an episode that summarizes the civil war.
*V: An alien invasion, in which the aliens literally wear human skin to make themselves appear normal. Aside from eating mice and things, they institute fascism. The series is all about forming a resistance against them. There is also a reboot of V, but I don't recall which series got to their conclusion.
Considering the shadow fleet, attempted assassinations, and assorted sabotage Russia has committed against the EU, I think a formal declaration of war would be warranted. The longer that Putin and Russia is allowed to live, the more likely that the US and Russia would spit roast Europe.
It is best to kill Russia before the United States formally declares war against the EU.
I think "Roosevelt Party" has potential. You can make two mascots for the ads, one being Theodore and the Franklin, each designed to appeal to the right or left among Americans. Theodore, for example, using guns to hunt down moose, advocating for national parks and peace with Canada.
Also, someone can commission an Epic Rap Battle between the two, who then dunk on Trump and Elon.
I think that if the Good Guys replace Nazi America with something new, they should engineer a new economic system where everybody's survival is guaranteed. If you have basic but genuine shelter, food, utilities, and so forth to rely upon, you can go out to protest or strike without worrying much about your wellbeing.
The current economy might as well be willfully designed to keep an economic boot on our necks. We can't afford the time, risk, or afford travel to do what is right. We should make money not used for survival, instead making it solely for buying luxury goods - a fancy car that isn't government issue, meals that aren't Generic Corn Flakes #1, and so forth.
Capitalism is good for supplying the demand for things that align with a person's hobbies and interests, but is utterly worthless when it comes to survival. We should fix that, by ensuring that billionaires cannot exist, and use their freed capital to fund a genuine UBI for all.
The one cold comfort I take away from this, is that the civil war against Dogey America would end faster than if the bastards were competent.
