I guess I'm banking on you being in particular subfields, but in all likelihood, you have a very bright side to look at. (I'm guessing you're in AP based on where you applied...) WUStL, Northwestern, and Emory are all great universities, but for most polisci subfields, Madison and Ohio State are rated more highly than those places that aren't going to be lucky enough to count you in their next year's class. There's a good chance I'll be at Madison next year, and I'm pretty stoked about being at a top-10 for American Politics that's doing great research in my areas of specific interest. And I'll still be stoked, even if I go 0-fer for the "big" schools sending out letters in the coming weeks.
Anyway, my point is that you got into some great schools that are probably rated more highly than some of the ones that rejected you, so don't read too much into where you're going to get in based on decisions you already know. And for the time being, you can at least know that you've got some good options on the table, which makes a lot of folks around here envious. Hope to see you in Madison in April!
