Does it make sense to double major in Public Relations and Political Science?

Both topics interest me however I’m unsure of what I would like to do as a profession, I just have an idea that I would like to do something along the lines of one of those two things. Im aware of the time and costs of double majoring- most advisors at my school recommend double majoring to reach the amount of credits we need to graduate. Does it even make sense to double major in both PS and PR? Could they be linked together for a profession?

Would you have to take out more loans to cover it?

You absolutely could link them together as a profession; I see no reason not to double major in them unless it will cost you additional money.
