Political Science is the study of a nation's government (power). This was something that I was interested in learning, so I took a few intro courses (Intro to American Gov't, and Intro to International Politics). I really liked them and seeing how government is set up, and how it affects people. Other related majors are Sociology and Public Policy. If you're interested in learning how groups are formed and organized, these majors may interest you. If you're simply interested in the major, I'd suggest to take a required course so you can at least get credit towards your degree while seeing if you like the major. I'd also speak with a professor or counselor to see if you want to pursue majoring in this field.
Here is something to think about: PoliSci, can lead to future grad school or work in the subjects/areas of law, city planning, social work, government, education, and politics. Law is part of every company, and the skills you learn are transferable to any area of industry: IT, entertainment, education, hospitality, medical.
