In my experience, poli sci majors either want to do pre-law and their school doesn't have that or convinces them this is better, have a major like finance or international relations and think double majoring will get them jobs traveling, or are completely 100% delusional. Sometimes, very rarely, they want to study anthropology but their family thinks they can't get a job with that, so they have to take this and become a politician.
