I doubt any ghoul runs for the senate or as mayor outside of a few ghoul centric areas
agreed, i'd be surprised if anyone from anywhere but dayglow was a ghoul in the government.
Lenny doesn't even change his sprite if you give him a suit of Power Armor without a mod.
none of the companions do, actually. it's kind of an oddity of the game. they basically just give NPCs a sprite and then stat them to match the armor, i'm familiar with the engine's background workings to a certain degree. it's why the enemies don't drop armor in the first place, they aren't really equipped, it's just a sprite assignment. lenny is the only ghoul companion, and the only ghoul you can PUT in combat armor in fallout 2, but if you're in combat armor in fallout 2, you're not going to have your face visible with its design. the ranger critter type is given the combat armor sprite, and the only one who doesn't wear that is the super mutant who just wouldn't make sense to wear it. i agree that there are no stated ghouls, but there's no reason to think there wouldn't be ghouls in the rangers at that point considering they let SUPER MUTANTS join, and the NCR shows no other particular bigotry toward ghouls. the average NCR citizen is probably more polite to ghouls than almost anyone else in the wastes. fallout 3 has it established that ghouls are treated pretty shitty, and vault city in 2 has a kill on sight policy for them. there are also only... what, 3 rangers in the NCR, and the others are on other maps throughout the wastes? the rangers at that point were still focused on their eradication of slavery in the region, i would think they'd take any capable gunmen they could get.
Point is that this is simply not the case around the main invasion force(the troopers) or even the "regular" Rangers, just the most elite units(which are usually specialized anyways) so even then that's a tiny minority probably centered around radioactive areas or kept around as reserves(Camp Golf).
agreed, ghouls are a minority without a doubt, even in the NCR, and there is very likely still prejudice around them. but the NCR doesn't kill them on sight, they live within the borders of the country, serve in the military in various positions, including highly respected special forces soldiers. contrast this to the brotherhood of steel, vault city where they kill ghouls on sight, even non-ferals. most cities around 2 where they're pretty mean to lenny as well if i recall. there's really no information either way about when ghouls were integrated into the NCR military, but it seems very silly that the rangers would allow a super mutant but not ghouls. either way, super mutants would be even rarer than ghouls, the only reason they're so present in the newer games is brand recognition. there's no reason for there ot be this many enclaves of supermutants around in the first place, they were originally just a thing being experimented on in a secret government facility in the mountains, but now every town in the goddamn wastes has an FEV canister poisoning its water supply or some shit.
my original point was just that the NCR was probably one of the least bigoted places in the wastes to live, outside of actual ghoul settlements. i was just commenting that the NCR doesn't have a distrust of mutants compared to many other groups in the wastes. sawyer is quoted as saying (with no source lol, thanks redditors) "It's hard to brainwash people who have been alive for a hundred+ years. More importantly, non-feral ghouls and SMs are also a tiny fragment of the population. Caesar doesn't really consider them to be that relevant in the overall struggle for the Mojave." so, he seems to think that as of new vegas, the legion is simply unconcerned with 1% of their population being mutated, because they have a much bigger and more pressing problem. the legion also definitely kill some super mutants because they have the centurion armor cobbled together from high level enemies from other factions, bits of which are from super mutants, so they've definitely got no problem killing them, and it COULD even be a right of honor or something. interesting thing to think about.
