Is There a Better Choice Out There?

If a voter looking out at a set of choices thinks that they are maybe not equally bad, but he's like, I'm sure there could be a better choice out there than the ones that have been offered to me. That seems to bring further epistemic complications in the sense of how do you go about figuring out where to go for that information given that there could be conflicting views. How does a voter answer that? Because it seems like we've just kind of have pushed the expertise question just down the road a bit.
