I have this headcannon that after everything while annabeth works towards her architecture dreams Percy gets into politics. Think abt it, he knows what it's like to have a crappy existence, he has always always fought for the underdog, he tries to side with vulnerable people and make their voices heard, he stands up to the bullies , he has definitely faced scarier things than aging conservatives who refuse to bring any changes, he has a lot of experience leading people and pushing people, he gets a lot of support from his friends and other campers, he genuinely loves his city (tlo) and you want to tell me that the boy who demanded that the Olympians pay child support, who called out the school administration in SoM abt their treatment of Tyson, who has seen firsthand how people can overcome centuries of rivalries if they put in effort, tell me this boy wouldn't be the shining beacon of hope for the young people of new york, he has annabeth and Reyna reviewing his policy and giving him advice, piper writing his speeches, he asks Grover's help while drafting environment-related policy, when new campers ask if they knew any prominent half bloods Chiron proudly tells them that the mayor of nyc, who has a pristine record and a massive support base blew up the bathrooms on his first day at camp.
((and his choice of affiliation very much reflects his favorite color,,,just saying))
