Since you’re in Colorado, you may want to look at WUE reciprocity schools for safeties.
U of Utah has very similar racial/ethnic demographics to CU Boulder, but a less affluent student body. The Honors College has its own very-spiffy housing, and particularly robust programming, with year-long Praxis Labs that grapple with a variety of societal issues and could enhance a poli sci or econ degree. The location in the state capital offers a lot of opportunities. It would be very affordable, between merit money and either the WUE discount or the path to residency after the first year.
Others WUE schools to look at could include UNR, Western Washington U, Cal Poly Humboldt
