The politics in Lancer the mech pilot TTRPG seems center left to me. A good way to explain what's going on in that game's universe is with this overly long metaphor:
Imagine an alternate history where Nixon somehow beat JFK Jr to the white house, and once in office he lets Kissinger go nuts setting fascists up on an accelerated schedule. That's what Union's Second Committee was like. Then Tricky Dick procedes to nuke Vietnam a couple times. That's the Hercynia Crisis and that FTL Piston weapon launch. JFK and company ride the shock and horror of approaching nuclear war into office on the promise of de-escalation and enforcing civil rights, and they deliver. That's the coup that formed Union's Third Committee. Kissinger, Nixon, and the entire pentagon/raytheon corp take over NASA in Cape Canaveral, Florida where they form a tolerated corporatocracy in exile. That's basically Harrison Armory on the planet Ras Shamra. Now a United liberal-leftist front of America is actively trying to tear down dictatorships around the world that Kissinger set up (he got assassinated at some point in this time line) and replace them with socialist democracies. That is Union's Justice/Human-Rights Department and a few other government branches. So far they've had some success although people are pointing out that it's a bit hypocritical that the liberators are using weapons from corporate conservative states where civil rights are discretely curtailed. That's what's driving political discourse in 5016u in Union's legislative body, the Central Committee and it's myriad political parties.
So yeah Lancer's political intergalactic landscape is a bit like modern day? Except also cthulhu is giving out reality-breaking tech to militant civil rights advocates and random civilians? That's what HORUS basically is, btw.
Now that I've written this out, it would make for a good american alt-history with mechs campaign in Lancer...
