Interest in IR/political science

<p>I've got a year left in my BA, my marks are in the C+-B-/B range, and I'm thinking that when I'm done, I want to pursue a masters in something political science -y.
I've got volunteer experience working with ESL students at my current University, I'm also a member of the Canadian/International Students club.
I've also been kicking around the idea of studying abroad (I'm Canadian, but IDK if the US if is "abroad" enough, if you know what I mean)
Is it realistic that I would have a chance at all with those kind of marks?
and Suggestions for things to look at would be good. k thanks.
(I know, really. its not <em>important</em> right now, except I don't want to be totally surprised/stuck/screwed in a year)</p>

<p>There are some schools out there that take GPA less than 3.0. Take a look a small state schools.</p>
