There are books in Career Services titled "Jobs in ______ Degree". They have pretty much every degree possible. Go to the front desk and ask where to find it.
I would say an internship is good experience. I worked in Ottawa for the summer in an internship with the federal government. I have since changed my mind on what I want to do for a career, but it was a great experience and it would have been amazing for someone going into a political/government career. Check Oscar and various government job portals for internship listings.
