Congrats on a great record. It’s hard to answer this - because all colleges are different.
What do you seek in a school?
Your UC won’t be seen at the UCs and likely UW.
I think, if you’re ok with UCR, UCM and UIUC, you’ll be ok. If you went for UIUC as a poli sci, it’d be safe I think - but that’s no reason to go. I think you’ll be safe with UW because they only have a DS minor and all can take and you’re a likely for poli sci. Does that combo work for you ? Study curriculums everywhere and not just names
Depending on your needs, there’s plenty you could apply to - but you have enough and I can’t chance you on the UCs, but you might be fine there.
You have UW….so you like the city. Look at Georgia Tech and Minnesota plus very strong in social sciences U of Arizona.
You like the smaller cities like UIUC and Purdue, look at WUE eligible Oregon State. Or UGA, strong in political science fields.
If you like Stanford and you like the idea of a minor in DS with a major in Poli Sci (like UW), maybe add a Rice as a reach. Emory is another reach - has a Quant Sciences major and you can add a Poli Sci track
If you apply to the list as is, I’m confident you’ll have options. As you can do Poli Sci most anywhere, I’d start with DS - but it will be a harder admit - at schools like UIUC. But better to start in it and leave if you don’t like vs. vice versa.
And data science programs are different - not all the same - so check the curriculum of each you look at to make sure it matches your desire. Most Poli Sci programs will have a data component, some with potential for deeper study than others.
For example, American U has a Political Analytics major (BS Data Sciences for Political Science), UTK a Policy Analytics major,
Penn State has a Social Data Analytics Major which they describe as is an interdisciplinary major designed to prepare students for careers that use “big data” or “social data” to tackle social and political problems. The SODA major combines political science courses with courses in statistics, mathematics, information science, and computer science. So that might be a great one to look at - fine school in both disciplines.
Miami of Ohio is another with a Data Analytics program with Poli Sci concentration.
Just more to look at - frankly, most schools will be fine - but some may have curriculum more attuned to your desires and rather than just pulling up names, I’d look deeper at the course offerings/requirements within each major/minor to see if they align with your desires.
Good luck.
