Why MIT? Even though you say you’re “anti-CS,” I suspect you must be open to a quant-heavy public policy program, if MIT is on the list. As such, you might consider both Georgia Tech and Emory:

Lots going on politically in Atlanta, and both of these programs are rigorous and well-respected. OOS full-pay for GT would be within budget, and Emory would hopefully give enough aid (run NPC). It’s slightly less reachy than the Ivy+ schools
Also seconding (thirding/fourthing?) William & Mary.
Absolutely do not bother with the UC app, which is onerous and which, best-case, will lead to acceptances you cannot afford and don’t even like as well as UF. If you want more California options besides Stanford, run the NPC’s for USC (B.S. in Public Policy Curriculum | USC Price School) and Claremont McKenna (which is smaller than the schools you’re considering, but it part of the Claremont Consortium, with around 7K undergrad total, and is particularly known for its Government and PPE programs).
Good luck!
