<p>I agree that it’s very important to have a deeper understanding of the field you hope to cover, as well as the marketability of a second language, but there are a few other things I would keep in mind. First, writing ability is CRITICAL to all fields of journalism (even broadcast) so make sure you build this skill. There’s no point in being an expert in political science if you can’t clearly communicate a complex idea or event in 400 words or less. And yes, the portfolio is the biggest key to getting a job after graduation. It’s not just about showing good writing and knowledge–it’s also proof that you can do all that under a tight deadline, get it right, know AP style, and can get the right people to talk to you. More than half the battle in journalism is getting the information, not just writing it. I know lots of journalism students who double major in the field they hope to cover (poli-sci, wildlife bio, etc).
I know this didn’t provide a clear cut answer for you, but I hope these thoughts are helpful.</p>
