Best CA colleges for pre-law/Political Science undergrad?

I’m looking to transfer to a 4-year university, after finishing community college for undergrad, so either a UC or CSU. I don’t want to attend a college that’ll leave me too in debt, coming from a low income background. I plan on working in college too, to earn some money. I’m really interested in Berkeley, or USC, but I fear those are a reach, and will cost too much, especially when law school is costly.
