I have a really hard time seeing Phil going Right-wing politically. The big draw for Phil being an AnTardfa analchest souper slopper Commie is that he wants free shit without working for it. Phil is a massive hypocrite, but switching to the side that wants to cut back on social programs as much as possible and values hard work and earning your own way in life is not something I can feature Phil doing.
Nah, the main attraction for Phil isn't getting free stuff from the state, its the imagery of being a "bad ass" revolutionary, and the alt.right paramilitary cosplayers definitely offer him that. He likes authoritarianism. He even had an outright Nazi fetish, so he'd fit right in with the edgy 14 year olds on 4chan. Hell, even though we stereotype them as right wing, a lot of these guys buy into the myth that they are owed something simply for being white. They claim America is "their country," and that blacks, Jews, Latinos and Muslims are "taking over," taking away all the jobs and women they are "owed." Obviously that sort of rhetoric would resonate with Phil. You aren't a failure because you're a loser, you're a failure because someone else is stealing your birthright.
Besides, Phil has a history of right wing views, at least back when he was a teenager. He still sort of displays such views. Most notably, he thinks Latinos are all dirty and poor, and has threatened to get people deported. His "liberal" crap is, at least partially, play acting. That's why he comes off as so insincere. He's basically acting out all the dumb stereotypes because he wants to fit in. Granted he doesn't really understand either right or left wing politics. I'm sure his young Republican phase was just him parroting back his mother's politics, or the suburban racism of his classmates, but its still kind of funny.
Honestly if Phil was just a little younger, he probably would have been exactly the sort of idiot who adopted right wing politics out of a sense of rebelliousness, and bought into crap like Alex Jones and QAnon. If there are alternate universes, some of them undoubtedly have Phils who are covered in shitty white power, Taylor Swift and 4chan meme tattoos, with Google translated German and Russian instead of poorly translated Spanish.
