This might be OK depending on your location and the government system in place. Voting for a single person that has to answer all questions sounds like UK or US to me.
Take a look at the Finnish or the Dutch parliament. 7, 8, 16 parties there? Independent (no-party) politicians too. Each one of them is free to represent people with specific needs and only focus on that.
Also keep in mind that some questions like "healthcare" and "welfare" may be less relevant too. It can be pretty much resolved (you can always promise to "increase doctors' wages by 30%!"). More specific issues remain.
Several Dutch people told me that firearms are common on ships under the Dutch flag. Given the number of people owning sea-worthy vessels this might be interesting. Do you know anything about this?
