In the politics I'd add a "how strongly do you care about this political affiliation" (scaled on 1-5, from "not at all" to "it's an important part of my identity")

A slightly longer option is to ask people to rate every political affiliation from 1 to 5. This lets us identify clusters better, as well as total political identification (if someone gives 1s to everything, that's the 'apolitical' option).
