The first three schools that I thought of after reading your profile were:
Claremont McKenna, Georgetown, and the University of Michigan.
Additionally, consider any of the 8 Ivy League schools (Brown, Columbia, Cornell, U Penn, Yale, Dartmouth, Princeton, & Harvard).
Also look at the course offerings at U Chicago & Northwestern University. (Easy to double or triple major at NU. Solid options if you want to consider Economics as one of your majors. Econ from either U Chicago or NU should open doors.)
Definitely consider UCLA based on your interests and residency.
If you feel the need to apply to a small, rural LAC, then consider Bowdoin College as you are a likely admit as a non-stem major even though Bowdoin does not admit by major; however, the school is overwhelmed by demand for STEM majors and probably would welcome a highly qualified government major.
