UC inter-Campus transfer

My son’s GF is applying to transfer from a UC to one of these- UCI, UCD, UCSB, UCSD, or UCLA for PoliSci. Her GPA is around 3.4-3.5 (Not sure exactly) and she has great extracurricular including working election desk and student government positions (including elected positions). She said her essays are decent but probably not fantastic. What are her chances?

She needs to ask her own questions. Asking for a Friend posts are not allowed for many reasons, not least of which is privacy. Closing.
