True, but when a particularly nominal explodes compared to other nominals, that, assuming there's no specific inflation issue in that area, is cause for concern.However you don't use nominal spending, because it's not adjusted for wage growth or inflation.
That's not entirely true. Performance in elections does address new voters or voters switching sides. Ask Bush Sr. He lost because of it.BTW: I didn't talk about a samle, when you talked about the elections. I was thinking about the actual election results. Then they don't judge the performance on the number of new voters you get, but they judge it by the percentage of voters you get.
