<p>What do people think? It seems to me, one major is enough. Why restrict your breadth and decrease your flexibility? Is a prospective employer impressed?</p>
<p>What kind of job do you want?</p>
<p>I have computer science and engineering degrees, so I can’t claim to have personal, first-hand knowledge about the value of Poly Sci or Economics degrees, but my impression is that there’s not a huge demand for either of those majors.</p>
<p>If you do end up in one or both of those majors, you probably should take as many statistics and quantitative-type classes as possible, since those have broad application outside of your degree. Mathematical classes also demonstrate you can handle rigorous subject matter.</p>
<p>(My wife has an Economics degree, but was very unhappy with the jobs that were available to her with it. It wasn’t until she got an MS in Information Systems that she was able to find work she was satisfied with.)</p>
