So one obvious suggestion is to look at some of the wealthiest LACs, which can be excellent for Poli Sci, preparation for law school, and have need aid competitive with the wealthiest private research universities.
And then the other obvious suggestion is to chase merit. With your grades and a high enough test score, you could be very competitive for merit at a variety of other LACs and private research universities, so would not in fact have to only look at publics as affordable alternatives.
If you would like specific suggestions along those lines, let us know. I note that even when you have high numbers, a good number of kids with such a list end up choosing a less Reachy private (or sometimes public OOS). Sometimes they don’t get admitted to any Reach-for-everyone college, but sometimes they also end up choosing a college like that over a Reach offer.
