I think you can go ahead and apply for PhD programs in political science and not a masters. I don't have my undergrad degree in political science and I took very few classes labeled as politics. I didn't list any research either. I got into a few programs and will probably be heading to OSU to study comparative politics or international relations. I think your advanced math will be a bonus for you wherever you apply.
I've been refreshing this site pretty obsessively ever since I discovered it last week. I have yet to hear from Yale and it seems more acceptances and now a waitlist have been posted on the results. I'm starting to worry I've been forgotten. I noticed that bigcheese and rlayla were in the same boat as of yesterday. Could you two post on here whenever you hear anything or send me a message or something? I need to know when to give up hope.
