that list sounds about right, I'm sure someone would debate #6-9, but #1-5 is right imo. I picked UCSD for poli sci because I live in SD and it's a great program. You also have to consider that Berkley, UCLA, UCSD & UCI all have poli sci departments that rank up there with the best in the world. There is a ranking here
http://www.politicalstudies.org/pdf/psr/hix.pdf that has UCSD #6, UCI #7, Berkley #11 and UCLA #14 in the world. The UC's have great poli sci departments.
