Edward "Eddie" Munson is an eccentric Hawkins High School student and president of Hawkins High's Dungeons & Dragons-themed "Hellfire Club" where he befriends Mike and Dustin. He lives with his uncle, Wayne Munson, and while the two are not seen onscreen together, it is made clear that their relationship is very close.
I think Eddie would be a good president because he always looks out for the little guy, the outcasts. He has a lot of compassion and empathy for others! He's capable of bravery, like when he saves Dustin Henderson. Eddie has a lot of courage, and he's always willing to help those struggling to fit in or emotionally distressed. There's a certain kindness in his soul that is very admirable.

Eddie would use pamphlets designed like DND booklets as his campaign platform. I like to think he would also produce podcasts to speak about his campaign but also use it as a way to connect with his followers. He would regularly cover topics he supports, as well as contemplating and hypothesizes changes he could make to the system with the help of others. He brings historical icons and members of civil movements in communities he supports to the podcasts to speak about resources and personal experiences. It's a casual but informative platform to connect with the citizens.
