When I talk about "entering government" in the weaknesses, I didn't mean nationally, I meant on a smaller local scale. My bad.
As for the constituency... let's go with Sagrado Corazón, a suburbanised town on the fringe of Montgri where the Kahurangi family are probably at their most socially influential. Rich neighbourhood. Includes some of the local rural area to make up the numbers, but it's certainly the wealthier kind of rural area compared to the kind that Sana's character represents.
